[jboss-jira] [JBoss JIRA] (JBRULES-2213) Planner:When there isn't an accepted move to pick, the DefaultLocalSearchSolver shouldn't terminate by exception but pick an unaccepted, doable move. Unless there are no doable moves, then it should terminate early.

This issue is partially obsolete now that using minimalAcceptedSelection, which means this can only occur if there are no accepted moves at all (of ALL possible moves).

Fixing this in 2 ways:
- If all moves have been tried and the forager doesn't have an accepted move, it WARNs and returns the best unaccepted move.
- If the decider returns a null nextStep (which basically means there are no moves at all), the local search phase will terminate itself.

> a random bad relativeSelection could select only moves that are tabu
> that no reason to stop, because the next relativeSelection could be great.
