Previously if you had been invited twice to use the app this management
command would fail with your address, since the email address was no longer
unique.
Now by unconditionally generating a new PreregistrationUser object we avoid
this problem.
To test, invite a user to Humbug via the webapp twice, then generate an
invite link for them manually. The latter operation used to produce a
traceback, but now works.

See PEP 328[1] for details. This feature was introduced in Python 2.5 and
will become mandatory in Python 3.

The previous situation was bad for two reasons:
(1) It had a lot of copies of the code, some of them missing pieces:
UserProfile.objects.get(user__email__iexact=foo)
This was in particular going to be inconvenient since we are dropping
the __user part of that.
(2) It didn't take advantage of our memcached caching.
