TrackSelectionView: Use same "isAdaptive" logic in updateViews and onClick.

Browse Source 
We currently do not show check boxes if the renderer does not support adaptive
switches between tracks in one group. However, we assume check boxes in the
onClick method.

Use same logic for both methods to be consistent.
