fix(trashBin): ensure the project is fully restored from the admin interface TASK-1645

[noliveleger]

📣 Summary

Fixed an issue where projects were not being completely restored from the trash.

📖 Description

A bug prevented projects from being fully restored after being moved to the trash, leading to missing or incomplete data upon recovery.

💭 Notes

Some unittests were apparently missing for this part, this PR adds two new tests. Moreover, part of kpi#5514 has been backported to this release.

👀 Preview steps

Bug template:

1. ℹ️ have a non-admin account and a project
2. delete the project
3. go the admin interface and put back the project from the trash bin
4. from the shell run this snippet

asset = Asset.objects.get(uid='<asset_uid>')
xform = XForm.all_objects.get(kpi_asset_uid=asset.uid)
print(xform.pending_delete)

5. 🔴 [on release branch] (from the shell) notice the output is True

This snippet should raise an exception

>>> asset.deployment.xform
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/srv/src/kpi/kpi/deployment_backends/openrosa_backend.py", line 1229, in xform
    raise MissingXFormException
kpi.exceptions.MissingXFormException

6. 🟢 [on PR] (from the shell) notice the output is False

This snippet shouldn't raise an exception

>>> asset.deployment.xform
<XForm "id_string">
