This addresses an issue where someone can “takeover” an account with only
a User’s email and a User’s previous ticket number. Once they get access
to a User’s ticket they can go to the Ticket Owner’s profile and change
the email to whatever they’d like. This adds a check on the profile to see
if the User is a Guest User. If they are a Guest then it kicks them back
to the ticket view. If they are the actual User it will let them view the
profile.
