ibaker 5030145c8f Use a shared keyForField implementation in track selection parameters
The current setup with distinct, private `keyForField` implementations,
leaves open the (theoretical) possibility of a clash in the `Bundle`
keys used by the superclass and subclass. This change brings
consistency with our only other extensible `Bundleable` type
(`PlaybackException`).
