Running nearbySelection with PHASE cacheType causes UnsupportedOperationException

Description of problem:
Planner throws out this exception:
java.lang.UnsupportedOperationException: null

Steps to Reproduce:
1. Use any TSP example
2. use local search below:

<localSearch>
<swapMoveSelector>
<cacheType>PHASE</cacheType>
<secondaryEntitySelector>
<nearbySelection>
<originEntitySelector/> <nearbyDistanceMeterClass>org.optaplanner.examples.tsp.domain.solver.nearby.VisitNearbyDistanceMeter</nearbyDistanceMeterClass>
<parabolicDistributionSizeMaximum>40</parabolicDistributionSizeMaximum>
</nearbySelection>
</secondaryEntitySelector>
</swapMoveSelector>
</localSearch>

3. run solver and see exception

as we talked on IRC, it shouldn't be possible to run solver with that configuration and it should fail-fast config evaluation.
