invites: Lock the realm when determining invitation counts.

This prevents users from hammering the invitation endpoint, causing
races, and inviting more users than they should otherwise be allowed
to.

Doing this requires that we not raise InvitationError when we have
partially succeeded; that behaviour is left to the one callsite of
do_invite_users.
