The UI freezes for a moment when launching Settings -> Online Accounts because g_application_register does slow I/O. After creating the GApplication's GDBusActionGroup, it queries the list of remote actions from the primary application instance over D-Bus to populate it. Fortunately, it's not necessary to fill in the GDBusActionGroup for activating a GAction. Therefore, this can be solved by directly using a GDBusActionGroup instead of going via a launcher GApplication. This does lose the platform data that the launcher GApplication would have passed when invoking the remote GAction, but hopefully that won't prove crucial. The loss of error handling doesn't matter. g_application_register was the only fallible step, and it could have only failed while querying the list of actions from the primary, something that's not needed anyway. If anything, it simplifies the code. Fallout from 556a9f30
