server crash when making robit spawner

Issue description:

So the server crashes when someone uses enderio powered spawners to make a robit spawner. Im pretty sure this happens because robits spawned this way do not have owners and to follow their owners (which robits do constantly) they are trying to get their owners uuid. This was discovered by a player on my server and now they have the ability to crash the server whenever they feel like it which is rather suboptimal.

Steps to reproduce:

  1. right click robit with enderio soul vial
  2. make powered spawner with soul vial
  3. power spawner

You are correct that robits are always supposed to have owners, what I would recommend is blacklisting them from enderio's powered spawners as if memory serves there is a configuration of some sort for what things can be put in them (or at least for what can be put in soul vials).
