Fix bug in router2 where router may give up too early.

Was introduced in #612.  The logic before was intended to prevent the
router from terminating early when not using a bounding box, but the fix
in #612 simply removed that, meaning that the router might terminate
early incorrectly.  The solution here is to only use the toexplore
hysteric once a solution is found.
