Fix constraints for collapsed layout

The missing constraints for the time views would cause the play/pause
button to be laid out incorrectly in RTL mode. Added values to match the
prev/next buttons (same as the expanded layout). Also removed code that
was changing visibility of these in code since the time views will
always be GONE in the collapsed layout
