Remove reactions to a user when deleting the user (#15724)
* Remove reactions to a user when deleting the user

Fixes #15245

---

I have no idea why `create(:vomit_reaction, reactable: user)` gave a
validation error about category being invalid, but `build().save`
worked fine.

* Move relation details to reaction scope `for_user`

Add a user method to access this by passing self to reaction scope

* Create a moderator when flagging user in factory

This might be a missing requirement in the reactions factory - but
this suppresses an error about invalid category I was getting when
setting a privileged reaction on the user via

    create(:vomit_reaction, reactable: user)

Everywhere else it looks like we do this with `user: moderator` (where
there's a trusted user in the surrounding context).

* Move trusted user requirement into vomit_reaction factory

* Add a data update script to remove reactions to deleted users

This cleans up the remaining invalid references and should make the
change in #15249 obsolete (i.e. we don't need to limit the view to
exclude items that no longer exist).
