Updated uses of user ID to nullify on delete.
Added testing to cover deletion of user relations.
Added model factories to support changes and potential other tests.
Cleans existing ID references in the DB via migration.
Added since we can't always be sure of future image usage, and in many
cases we don't generate ahead-of-time.
Also:
- Simplified image handling on certain models.
- Updated various string handling operations to use newer functions.
- Reduced app settings down to what's required.
- Used new view-shared $locale object instead of using globals via
config.
- Aligned language used to default on "locale" instead of mixing
locale/language.
For #4501
- Moves guest user caching from User class to app container for
simplicity.
- Updates test to use simpler $this->users->guest() method for
consistency.
- Streamlined helpers to avoid function overlap for simplicity.
- Extracted user profile dropdown while doing changes.
- Updating formatting.
- Tweaked truncation to roughly match elipsis char to width used.
- Updated testing to use existing helpers, and ran check as admin user
to avoid name conflicts.
- Adds filtering to the watched items list in notification preferences
so that deleted (recycle bin) items are removed via query.
- Adds relations and logic to properly remove watches upon user and
entity delete events, to old watches in database do not linger.
- Adds testing to cover the above.
Did not add migration for existing data, since patch will be close to
introduction, and lingering DB entries don't open a security concern,
just some potential confusion in specific potential scenarios.
Probably not work extra migration risk, although could add in future if
concerns/issues are found.
