    lib: Fix updating device and adapter list after initialization
    
    Patch 17983ace (lib: Use GDBusObjectManager) only added listeners for
    interface-added and interface-removed. However, as GDBusObjectManager
    simplifies the API to emit object-added/-removed those have to be
    listened for changes too.
    
    Without this the list of bluetooth devices and adapters is never updated
    after the initial object listing.
