  Log Message:
  -----------
  Allow retransmissions and wait for reply/timeout on canceled branches.

Do not do anything about branches with no received reply; better continue the retransmission hoping to get something back; if still not, we will generate the 408 Timeout based on FR timer; this helps with better coping with missed/lated provisional replies in the context of cancelling the transaction

Many thanks to Maxim Sobolev for bringing this under discussion.
