[animation] Do not connect to ::completed multiple times

Browse Source 
The clutter_actor_animate*() family of functions should only connect
to the Animation::completed signal once, during the construction of
the Animation object attached to the Actor. Otherwise, the completed
signal handler will be run multiple times, and will try to unref()
the Animation for each call -- leading to a segmentation fault.
