Ran https://github.com/python/cpython/blob/3.7/Lib/lib2to3/fixes/fix_asserts.py after adding the missing methods (assertRegex and assertRaisesRegex) on ERP5TypeTestCase.

Also ran a custom fixer rewriting
 
```py
self.assertTrue(a in b)
```

into

```py
self.assertIn(a, b)
```

Unindexation happens in a transation after the corresponding document was
deleted. So there is no context available to check the type of the deleted
document. So these filter expressions are meaningless.

    method_map = {True: 'assertIn', False: 'assertNotIn'}
    method_in = meth.value == 'assertTrue'
    if 'not' in str(needle.parent.children[1]):
      method_in = not method_in
    meth.replace(Name(method_map[method_in], prefix=meth.prefix))

    needle.parent.children = [needle, Comma(), haystack]

so that we can run 2to3.fix_assert

This updates the change to 32cead86 (xhtml_style: set a bottom
margin for dialog action, 2019-05-31) that got impacted by a rule
added on html and body in 5dde17a5 (xhtml_style: make editors in
bottom group use full height, 2022-08-22)

this code was latin 1, causing issues for refactoring scripts

Form.__call__ replaces page template call, so it is also responsible
to set the content type in response.

With Page Templates, ZopePageTemplate._exec (called by
Shared.DC.Scripts.Bindings.__call__ and _bindAndExec) sets the
response content type and calls pt_render. Form.__call__ also calls
pt_render, so to behave like page template, it should also sets the
response content type.

In erp5_xhtml_style, we don't notice this, because global_definitions
contains a setHeader call to set content type to html.

Check that it correctly includes the web page and sets the content
type header.

it would be good to rewrite this in a page template

This method converts the HTML, so it should escape nasty HTML tags.

Also add missing escaping when inserting the base

and move it to erp5_administration, this is not a "core" feature but
just a developer tool.

It was used in a few tests, move all the tests in testERP5Administration

Make sure we don't set grouping reference on lines that have a valid
group only for source (or destination) but not for the other side.
