add date and key images to SignedOffer

arbitrator retains failed trades after reserve tx received
legacy ui shows trade details including reserve tx, with or w/o contract
fix npe searching arbitrator tickets due to null payment accounts
synchronize offer book list items
fix npe before key image poller initialized
