This includes a hack to preserve humbug/backends.py as a symlink, so
that we don't need to regenerate all our old sessions.

If you entered "stream:Denmark " in the search box, we would show
you two suggestions for "stream Denmark", despite our duplicate
detection, because we didn't canonicalize the suggestion that is
literally based off the user typed query, and so the other way
of generating the "stream Denmark" suggestion created a duplicate.
Now all the suggestions we generate are canonicalized, so the
generalized duplicate detection can work.

This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
