Fix reversed preposition in the audit log's user-removed row

audit_table.userRemoved read 'Removed {username} to the {channelName} channel'
-- it described a removal as an addition, right next to audit_table.userAdded
which uses the same wording with 'to'. In an audit log, a row that states the
opposite of what happened is worse than a typo.

Nothing needs re-translating. All 20 non-English locales already say 'from'
(von, du canal, から, из, khỏi): every translator silently corrected the English
rather than reproducing it, so this makes the English match translations that
were already right. The single exception is en-AU, which is a deliberate copy
of the source and therefore inherited the bug; it is corrected here too.

I previously flagged this as needing 21 re-translations. That was wrong -- I
had not checked what the catalogs actually said.
