Given that the authorization system is db-based, review all code paths directly looking up the collection by uuid in the collection catalog that currently do not include a db name.

The output of this ticket should be the following:

• If it would always be possible to lookup by db name + uuid, get rid of the only-uuid lookup method
• Else, make sure that all the paths looking up only by uuid are internal and always safely used after correctly checking the authorization on the db
