Selecting an entity that is despawned during the task results in an exception

[graefjk]

The ICGE throws an EntityNotOnFieldException when an entity is selected that is despawned during execution of the task method. This behavior comes from the fact that the entity inspector tries to update the position of the coin after it is despawned and the getEntityPosition method throws a EntityNotOnFieldException.

How to reproduce:

• run the ManualStartSimulation.java
• select the coin in the entity inspector
• press play
