violates foreign key constraint "fk_rails_f7dfda8c51" on table
"protected_tag_create_access_levels" DETAIL: Key (id)=(1385) is still

Merge branch 'pawel/update_prometheus_client_gem_to_improve_performance_when_rendering_metrics' into 'master'

- Adds a new `ProjectMovedError` class to encapsulate that error
  condition. Inherits from `NotFoundError` so existing rescues should
  continue to work.
- Separating that condition out of `NotFoundError` allowed us to
  simplify the `raise_not_found` helper and avoid repeating the literal
  string.
- Spec makes use of `ERROR_MESSAGES` hash to avoid repeating literal
  error message strings.

- Combine multiple `it` blocks into one where it made sense
- Use `set` for the top-level User record
- Refactor permission matrix tests

Guess the modes based on the following:

1. If the file didn't exist, it's zero.
2. If the diff contains 'Subproject commit', it might be a submodule, so 0600.
3. Otherwise, it's 0644.

This isn't perfect, but it doesn't have to be - it won't change file modes in
the repository.
