Subject: [PATCH] ob-watcher: tackle stale orders by first removing all of them

when checking for timed-out counterparties (or refreshing the
orderbook), stale entries are preserved because those peers
disconnected prematurely. This fix prevents that issue by
first removing all entries before requesting for the orderbook.
