[BUG] Nullref when shortcut not possible to register #29https://github.com/Hofknecht/SystemTrayMenu/issues/29
-nullref exception still possible -> do not start contextmenu before shortcut registered
Removed code execution path that can never happen: Icon of an lnk's directory will be loaded directly within first call of ReadIcon, no need to call it again and then break as icon already exists
