Fix finding AnimationPlayer in scene import 

The scene importer always assumed that the AnimationPlayer is called
"AnimationPlayer".

This is not always true: for example the GLTF importer just creates an
AnimationPlayer with the default name, which may be "animation_player",
depending on the project settings.

This fix instead chooses the first node that is an AnimationPlayer, and
warns if there is more than one.
