Python plugin latent taskgraph crash

[getnamo]

If you end play with a latent taskgraph (call back to game thread from python), the plugin will get an invalid object and crash. Will likely need a WorldContext test for scheduled latent tasks.

See:

https://github.com/getnamo/UnrealEnginePython/blob/master/Source/UnrealEnginePython/Private/UEPyLambda.cpp nope this is dormant, using the UEPyEngine function instead atm.

debugger is pointing toward https://github.com/getnamo/UnrealEnginePython/blob/master/Source/UnrealEnginePython/Private/UEPyEngine.cpp#L528

Invalid world context comes to mind...

fixed in e7dd780

Note that run_on_gt does not do any checks by itself, the user will have to take care and ensure it's called inside a game world or guard it by their own method.
