_clutter_actor_get_animation_info() creates a new info when the actor
currently doesn't have one. That's unnecessary and wasteful in case
where we only need to check for transitions to remove, so switch to
_clutter_actor_get_animation_info_or_default() that falls back to
an empty static info.
Fixes: c250f602bd ("clutter/actor: Remove transitions when removing an effect")
