Create route for resending an app invite

Replace ApplicationInvitations._update_status() with revoke() because multiple functions used _update_status() and it was causing app roles to be disabled when they shouldn't have. Now app roles are disabled within the revoke function.
Updated Invitations.resend() to accept user details so the invite info
can be changed in the new invite
