Models with workflow state "default" are only considered in composition if no
other valid model is defined. This allows to implement "ingest anything"
policy in wendelin.

Add PortalType field to distinguish different types of Python Scripts, add referencence and use source code editor

Pattern: SIT_1 => RSPL => SIT_1.

Also, this reduces the complexity by not checking objects twice.

Functional Tests: Migration to PDF.js in recent Firefox clears preference to save automatically PDF files to the disk.

- <a href="c"> was not transformed to absolute url

If we don't propagate movement_list_mode to catalog, this prevents
catalog from raising an error about this unknown parameter.

It's better to create new objects using same script rather than
keeping 2 scripts that try to do the same thing: Folder_create
(script used to add in case we create new object using the icon next to actions bar)
did not support the getRedirectParameter API. We now do all the work
related to adding new object in Folder_create itself.

This is for backward compatibility.

Also add some explicit tests for check_consistency, it was missing in
the first place.

by adding  timeout in order to prevent an error from changing page before

When pusing to for_testrunner_1 branch, we often have this failure on testFormPrintoutAsODT:

```
======================================================================
FAIL: test_field_replacement_with_variable (testFormPrintoutAsODT.TestFormPrintoutAsODT)
test variables replacement in ODT documents.

```

After some investigation, turned out that:
* tests where always failing when running by `COMP-2544-3Nodes-ERP5PROJECT2` testnode
* This machine uses `SystemV/CST6CDT` as timezone
* the test fails in the same way when running locally with `TZ=SystemV/CST6CDT`

I belive this fixes, I tried running under `SystemV/CST6CDT`, `UTC` and `Europe/Paris`  TZ and it passes for all cases.
