dialog: fix bug when detect_spirals enabled
If detect_spirals enabled and the caller sent an Invite which received a
negative response and then immediately sent another Invite with the
same callid and tag, the module did not create a dialog record for the
second Invite. It wrongly concluded that the Invite is spiraled. This
resulted in missing CDR for that call.
Behavior observed if the first Invite has a small Session-Timer interval
and receives a 422 reply. When the phone sent the second Invite with a
larger Session-Timer, which could have been successful, it was not recorded
by the dialog module.
