Description

While reviewing the patch for #28918 and reflecting about #28939 I noticed that the refresh_from_db() method was duplicating the work the routers do when an instance hint is provided.

I figured out that we we're better of using db_manager(using, hints={'instance': self}) in this case which would also have the benefit of passing down instance as an hint to possibly defined custom routers.
