So different test suites can have a same named sequence without
theme colliding with each other

When installing the tested software failed, no test result lines
have been created, this should have status FAILED.

person reference contained the username, so test was also passing, but what we
really want to test is that the username is in the mail body.

ee64d50c (patches/CookieCrumbler: update patch for CMF 2.3, 2019-09-09)
introduced a NameError, getRequest was not imported.

All reports were properly including movements from the last day,
except general ledger which were only including movements made
without hours:minutes (at midnight). This was not a problem for
manually entered transactions, which are usually made at 00:00
but when transactions are entered with hour:minutes they were
not included.

BMP are not compressed and use more disk space than PNG.
The trick is that ERP5 uses by default a quality of 75% on images ([this is
default on propertysheet]) so we need to dump the image with maximum (100%)
quality.

Update also assertion message to not include the full base64 image in case of
difference, use a short assertion message and save images in log folder.

[this is default on propertysheet]: https://lab.nexedi.com/nexedi/erp5/blob/2f9b67fae3ac59955231d4191a34134ff1b6079a/product/ERP5/bootstrap/erp5_property_sheets/PropertySheetTemplateItem/portal_property_sheets/HtmlStylePreference/preferred_image_quality_property.xml#L56

When rendering reports, deferred style was only keeping request.other, but
some places, like Products.ERP5Form.ListBox.ListBox.getParamDict read only in
request.form, which caused different behaviours when rendering reports
directly or in activities, because when rendering in activities request keys
that the report dialog might have pushed were not preset in request. They
were of course present when rendering the report directly, because this was
the same request, so this lead to different behaviours wether reports were
rendering in activities or directly, like we could observe in 7058ab6f
(accounting: fix grouping option of GL when running in deferred mode, 2021-02-25)

This change deferred style to properly propagate request.other and
request.form in all activities of reports.

Calculate link to allow Nexedi developers access the ERP5 fields, forms and form actions from it.

* erp5 form gadget handle links to access from and form action
* label field gadget handle links to access field configuration, title
and descriptions translations
* page action handle all links to access workflows and portal type document
* add generic function to merge action with raw actions by group

* Add sample of action that allow uses access slideshow from ERP5JS

ERP5 uses a mix of context.REQUEST and Products.ERP5Type.Global.get_request(),
which now uses zope.globalrequest.getRequest().
CMFActivity reconstruct the original request before executing activity, so that
the activity is executed with a request equivalent to the request at the time
where the method was activated. For this, context.REQUEST was properly restored,
but get_request()/globalrequest was only restored when the REQUEST had some
Accept-Language header, so that it replays the language negociation for
Localizer.

With browser requests, I guess every browser pass an Accept-Language header (
according to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language
all major browser support it), but within unit tests such header is not present.
So this lead to activities with unit test requests being slightly different,
because as they don't have Accept-Language, context.REQUEST was set, but the
global request was not set, so they were running with two different requests
in context.REQUEST and global request, leading to some problems for example
with formulator fields.

as an extra safety measure

and also addition of comments

instead, check for the specifically expected Exception
and in that case return with a warning

Commit updates also testDelete of listbox_zuite accordingly

See Alarm_generateReportDocumentList for the full API and the test for example
usage.

This enables reuse of deferred style API to produce a report, but do
something else with the report.

Split a reusable test base class and use self.username variable.

Also don't set username as reference on person, this is no longer needed
since ERP5 Login.

7a9d47adff (authentication_policy: fix display of password expiration date, 2021-03-25)
was wrong, the date was not properly substituted in the message.

This constraint had a TALES expression making it not apply on invalidated
accounts, but during the transition invalidated -> validated, when the account's
consistency is checked, the account is still in invalidated state, so that
check was ignored, making it possible for users to validate an account without
and account type.

- Use Message, so the comment is translated in display time
- Do edit only if we have some objects deleted from ZODB

- Remove useless conditions of "if True"
- No use to use try-except-else, since all except branches
either raise or return
- Remove trailing whitespaces
