FieldTypeUninstallValidator lists the same content revision 2x if it the default revision

For some reason gitlab gets a 404 when linking to my merge request I just created. This can still be worked on while that gets figured out.

I pushed fix but the test will need to be updated.

Now that 📌 Expand test coverage in FieldUninstallValidatorTest Needs work is merged we need to

1. Take the version of the test from 0.x
2. Remove the duplicate reasons from the array
3. Remove the todo pointing to this issue and add the new assert to ensure we don't get duplicate reasons

Looks good to me!

Assigning to Wim because I can't actually to the merge without another gitlab approver from CODEOWNERS.txt

Automatically closed - issue fixed for 2 weeks with no activity.
