reInvite after 491 response is not proxied

[rhondahollis]

When Drachtio receives a resend of a reInvite that had originally resulted in a 491 Request Pending, the INVITE is not sent on to the other leg. The last thing I see in the log for the handling of this reInvite is:
2023-11-16 19:24:35.105989 SipDialog::setSessionTimer: 98833900-ff58-123c-19bc-0050569252d2 Session expires has been set to 90 seconds and refresher is them

Full log has been sent to you.
