    Avoid g_critical() errors when unable to connect to upower
    
    This removes two g_critical() errors that are seen when running the
    tests in CI.
    
    Before:
    
        (tracker-miner-fs:7050): libupower-glib-WARNING **: 14:31:50.109: Couldn't connect to proxy: Could 
not connect: No such file or directory
    
        (tracker-miner-fs:7050): GLib-GObject-CRITICAL **: 14:31:50.109: g_object_unref: assertion 
'G_IS_OBJECT (object)' failed
    
        (tracker-miner-fs:7050): GLib-GObject-CRITICAL **: 14:31:50.109: g_object_unref: assertion 
'G_IS_OBJECT (object)' failed
    
        ** (tracker-miner-fs:7050): WARNING **: 14:31:50.109: Unable to connect to UPower
    
    After:
    
        (tracker-miner-fs:12620): libupower-glib-WARNING **: 14:38:52.337: Couldn't connect to proxy: Could 
not connect: No such file or directory
    
        ** (tracker-miner-fs:12620): WARNING **: 14:38:52.337: Unable to connect to UPower
