This is still a work in progress

Until now, it was only possible to define the ID on properties, then the
reference was guessed from the ID. We even had constraint to make sure
when we define a standard "foo" property that the ID was "foo_property".
Then the reference "foo" was guessed for the ID.

This is not user friendly, it is more logical to make the ID non editable
and guess it from the reference. Therefore now the developer could define
the reference, like "foo", and the corresponding ID will be automatically
set.

- run computation before trying to get results
- always defined a section, it is mandatory in UI so it should be in tests

This is very convenient when we use portal_templates.upgradeSite to

usually used when we have a bt patching other bt.

Allows implementing user-based restrictions on classical ERP5-style
rendering.

This functional change should have been in a separate commit.

Commit accidentally reverted "IE use the latest rendering engine to
render the page". Reapply the change.
