[tests-only] [full-ci] Tests and fix for issue 39687

[phil-davis]

Description

These test scenarios will fail because of issue #39687.

I added the fixes to the code (see 3rd commit). CI should pass.

ToDo:

• add unit tests to cover this stuff
• test the case of a subadmin who has permissions over a user. The subadmin should be able to change email and display name always.

I'd also include the fix for the migration (commented in #39687 (comment)) as part of this PR. The fix should be just including null as default value for the getValue call.
It's also easy to manually verify that the problem is solved just by checking a fresh installation
