The post-delete signal on AlertWord clears the realm cache; when it is
called repeatedly, this results in re-fetching the realm object O(n)
times, where n scales by number of users in the database.
Disconnect this cache-clearing signal before removing the AlertWord
entries, and reconnect it afterwards. This is not thread-safe, but
this section is single-threaded. It is also probably unnecessary to
re-connect the signal, as rest of `./manage.py populate_db` does not
delete AlertWord objects, but cleanliness dictates doing the
re-connection.
This drops the time to repeatedly run:
python3 ./manage.py populate_db --num-messages=0 --extra-users=1000
...from 47 seconds to 36 seconds.
