Fix security problem with update_ticket view

@martin-marty Introduced a security flaw in this commit.

ecefd5e407#

and mixing the return types. This function returns both a Ticket object and a
login redirect. This is simply non-sensical and fails to actually login-redirect
non-authenticated users.
