Fix editor export plugins always causing resources to be edited.

- Remove the ', true' which always caused the if statement to be true.
- Add a new comparison before setting again the same array or dictionary back to the object. Not all objects are programmed to take into account that the setter could be called with the exact same Array or Dictionary from the class. This check ensures that scenario doesn't happen since it should be unnecessary.
