Fix tests in devcontainer by removing resolution center (#5702)

Since #5696 we don't need to load the resolution center early. In fact,
with #5686 this is even problematic for pytests in devcontainer, since
the Supervisor Core state is valid and this causes AppArmor evaluations
to run (and fail).

Actually, #5696 removed the resolution center. #5686 brought it
accidentally back. This was seemingly a merge error.
