breacharbiter: stop the stale contract when a live contract appears 

This commit modifies the logic of the contract hand-off within the
breachArbiter to ensure that only a single internal closeObserver
goroutine is ever active for a given contract.

This modification cleans up the logs in the case of multiple
reconnections and may possible eliminate some non-deterministic bugs
related to channel force closures.
