olly 6c6e256cfb TrackSelectionOverride: Remove select-all-tracks constructor
This constructor always does the wrong thing for non-adaptive groups
containing more than 1 track, because it'll incorrectly generate an
adaptive selection. Replace it with a constructor for specifying a
single track within the group instead.
