UPBGE: Load scripts and actions before converting scene during libload.

Previously the scripts where loaded after the scene was converted and
caused the python component conversion to failed because the script wasn't
reachable at the import.

This is fixed by moving the call to addImportMain before the scene conversion.
Similar behaviour is applied for the actions.
