bugfix uninitialized value in cs-animation-editing.c

[bpeel]

(issue originally reported on bugzilla.clutter-project.org by Antoine Roguez)

While playing with cluttersmith (creating + playing an animation and then
resizing the animated actor), I had a crash which, after investigation with
valgrind was caused by using an uninitialized value in
ensure_temporal_animator_handle (cs-animation-editing.c +419).

Please find enclosed a patch to fix the bug
