Short description of error
When animating armature override *that contains drivers*, actions added to NLA tracks are lost after saving/reloading blender file.

Exact steps for others to reproduce the error
1 - Load testCubeDriverNLA.blend (contains link to cubeRigDrivers.blend)
2 - Use "push down action" from the NLA editor to add current "ArmatureAction" action to a new track


3 - Save the file
4 - Reload the file: the NLA track is lost

This is actually a known issue/TODO, editing an existing animdata of an overridden data-block is not supported/implemented yet.

Linked object with drivers already have an animdata, while linked object without any driver or animation does not have one, so creating one in the override does work.
