Dumb-down avatar presence check in `avatar_url` methods

`avatar.present?` goes through CarrierWave, and checks that the file
exists on disk and checks its filesize. Because we're hitting the disk,
this adds extra overhead to something where the worst-case scenario is
rendering a broken image.

Instead, we now just check that the _database attribute_ is present,
which is good enough for our purposes.

Assert against `ActionMailer::Base.deliveries` relatively

- Closes #19496 
- Fixes `master` build


See merge request !5082

- Look for a `change` in its size rather than asserting against an
  actual size.

- This previously failed because another spec had an email in
  `ActionMailer::Base.deliveries`, which failed this `be_nil` assertion.
