RemotePlugin: Revert unnecessary invalidate() changes

Reverts some changes made in 9db8cbfb31.

The consequences of this changes are unsure, so reverting them for now.
Since a VST plugin's architecture is now detected before trying to load it,
this fix is not needed any more for 64&32-bit VSTs to work, as the
idVstBadDllFormat-message-mechanism was removed.

It should be noted however that the bug still exists, probably rendering
4fd8ecd7e4 ineffective.
