The original code inside ClutterActor that dealt with Transitions
stopping was written for the ::completed signal, thus the code was
correctly handling the lifetime of the instances; when we moved to the
::stopped signal, we assumed that it worked in the same way - with less
conditions to be checked, obviously, but fundamentally similar to the
::completed signal. Sadly, I screwed up the signal definition, and the
signal ended up calling our handlers, but not the default one that did
the cleanup and released references on the Animatable instance.
After fixing the Timeline::stopped signal, we can go back to the
previous code.
Thanks to Craig Hughes for the help in tracking down this mess.
