also str representation of unicode character is different.

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:
