Title: fix NPE with entity collision

No idea what causes this NPE, but with my plugin Dynamite http://github.com/cole2sworld/Dynamite ( binaries for testing available at http://ci.cole2sworld.com:8080/jobs/Dynamite ) if you throw enough dynamite around for long enough (completely random, but always happens eventually) you get an NPE due to the entity being null. This pull request should fix that problem.
