also str representation of unicode character is different.

The logic of the patch accidentally changed in 240a8d26 (
{,Propertied}User: Reduce the overhead from Developer role processing.,
2019-02-14). This used to be a patch to not consider 'Developer' as
a local role in SimpleUser.getRolesInContext , but it was changed to
not consider 'Developer' role at all - also as a global role.

SimpleUser are users from the the root acl_users, users from
erp5/acl_users will typically be PropertiedUsers, because this is a PAS
user folder.

Call the original method instead of copy/pasting the code

We still keep the following patches:
 - user: this is an ERP5 addition and maybe we use it in customer project
   code (if we don't I'm in favor of removing the feature, it's used in
   only one place in this repo)
 - call `self.changeSkin(self.portal.getCurrentSkinName())`. Maybe this
   is needed for CMFCore tests and could be good to send upstream, I did
   not check this part

This reverts commit 8d81b128a4f905609a00fdbb75e59d8c2edfa2d4.

commit message was wrong

This reverts commit bf230f1f.

Globals.DevelopmentMode initial value is False but it is initialized to True at
Zope startup (App.config.{setConfiguration,DefaultConfiguration}).

In the changes from ExternalMethod 2.13.1 -> 4.5, now ExternalMethod
define __code__ (and __defaults__) to a computed attribute calling
getFunction, but getFunction is different in our patched class, so
when unwrapMethod tries to get __code__, it will raise and mapply
will not consider the external method as being callable, so a simple
__repr__ of the ExternalMethod will be used as response body when
published.

By defining __code__ to something using our patched logic, this
problem does not happen.

There's also a TODO because DevelopmentMode is now True, which uses
a different code path which was causing TypeError, because getPath
returns None, which os.stat does not accept.

We now must use Zope4 to export business templates to commit on ERP5
master branch

Duplicating the id is bad. Checking the meta_type is not perfect, but it
is one step better.

Updating pandas to 0.24.2 revealed as :

      File "develop-eggs/astroid-1.3.8+slapospatched001-py2.7.egg/astroid/raw_building.py", line 360, in _set_proxied
        return _CONST_PROXY[const.value.__class__]
    KeyError: <type 'numpy.ufunc'>

when linting code referencing pandas. The problem is actually with
some numpy `ufunc`, such as numpy.sin, but we don't seem to have code
using it in the test suite.

Creating Stripe Payment Session and HTTP Exchange in the same transaction can raise conflict errors and when it happens, we already created the session on the Stripe side.

With this, when this happens, we receive one useless webhook to inform that the session has expired.

Also, batch_mode was removed because we only use it in tests. The tests were updated to use like in production.

This change will probably avoid the issue below:
