    coregrilo: Replace tracker source if the plugin is already loaded
    
    All grilo plugins are loaded at startup. However, TrackerWrapper may
    not be available yet. In that case, GrlTrackerWrapper is not
    created. Once TrackerWrapper becomes available, all grilo plugins are
    loaded again in order to instantiate GrlTrackerWrapper.
    
    However, TrackerWrapper may become available while the first tracker
    source is added. In that case, GrlTrackerWrapper is instantiated with a first source
    but a second source will be created by the second load_all_plugins
    call (a new tracker source is created everytime the tracker plugin is
    activated). Then, GrlTrackerWrapper won't get any notification because
    they will be associated with the second source and not the first one.
    
    This issue is fixed by replacing the GrlTrackerWrapper source
    everytime a new tracker source is created.
