Don't enforce metadata.desktop, cleanup constructor

Browse Source 
Makes it possible to use plugins that offer a metadata.json file.
Define the service type when falling back to the desktop file parser, so
the type system is proper.
Don't destroy a KPluginMetadata tuple to instanciate it right away.
