'NoneType' object is not iterable

Since 05210e87 (erp5_web_renderjs_ui: add LabelField support,
2020-05-26) we have label field support, so this labelfield is no longer
rendered with the fallback "read only field" gadget and markup is
different. Update selector to make the test happy.

this is useful for an intermadiate dialog that does not require submit
button but still top 'cancel' link works.

Fixes test failure:

    ======================================================================
    FAIL: testNamingConvention (testERP5NamingConvention.TestNamingConvention)
    ----------------------------------------------------------------------
    Traceback (most recent call last):

this report got broken in 2178cbed (pdm: fix pylint messages and
enable coding style test, 2020-03-09) there's no "Base" portal type.

This report has no test coverage, but the bigger problem is that the
graph from this report is not readable.

here as well we need to have body scripts after body for same reasons as
6b8e263b (monaco_editor: put body before head, 2020-06-01)

This fixes testDynamicClassGeneration failure since the migration of
IMovement (e8e5f273) which uncovered this issue.

ZODB Components: pylint: Generate astroid Module AST once for both the Component Module and its versioned Module.

This reverts commit 5b93b30f.

if such error occurs, this listfield show "You selected an item that was not in list" error message when save

- Add a Post interface so that we can use `Post` as a prefix for skins.
- fix pylint messages
- enable coding style test

See merge request nexedi/erp5!1152

See merge request !1150

Display a ParallelList field as a list of sub fields calculated with the hash script.

Keep previous HAL properties to keep compatibility for client without the JS implementation.

This should have no impact on existing code as pylint is ran on a named
temporary file anyway but it avoids useless checks for relative imports
and thus is slightly faster.

See merge request nexedi/erp5!1144

This is something we can do in TALES, it was supported in the old UI, so
we keep compatibility in HAL JSON API.

adjust tests now that the test component itself is found by catalog.

* Import Movement Document:
  + Event
    + MailMessage
  + Project
  + ImmobilisationMovement
* Imported by IMovement:
  + IAccountingMovement
  + IAmountGenerator
    + AmountGeneratorMixin
    + AmountGeneratorLine
  + IAssetMovement
  + IProductionMovement
* Used by MovementGeneratorMixin:
  + IMovementGenerator
  + IMovementList

Also, define providesI<INTERFACE_NAME>() on Base class for migrated Interfaces as
these needs to be available before bt5 containing the ZODB Component Interfaces are
upgraded (see also c86107bf). Otherwise, testUpgradeInstanceWithOldDataFs fails as
z_catalog_item_list (newActiveProcess() from upgrader) calls providesIMovement().

This also moves ImmobilisationItem and its interface from erp5_immobilisation
to erp5_core as ImmobilisationDelivery import them.

* Discount: Portal Type actually uses Resource Document.

We were only checking if the defaut charset or default collation were
same, but if anything is different in the table options, we should
update it.

Also add a missing test for updating column comment

Not a proper tool to search source code, but makes it possible to search
for source code in component.

test_apply_model_filled_computer_batch_mode did not pass batch_mode
and was wrongly checking that result is True

Test was passing, because without batch_mode Computer_applyComputerModel
returns Base_redirect, so the result is indeed evaluated as True.
Yet in this case we should expect False, since no changes are applied

this is required for stock browser to work in ERP5JS with Component
portal type

and make it possible to create the test delivery using a component as
resource
