Reloads the action source. This method is useful when you want to find externally stored action sources that have become disconnected from a clip.
You can also use this method to reload a source which has been offloaded. If the source has external storage and the file is valid, the source removes all current AnimationSourceItems and reloads them from the source file.
Reloading the source disconnects all action Clips that use this source and reconnects them (this happens even if the source is stored internally or if the file is invalid). Once the paths are updated, reloading the source reconnects everything correctly.
