Add play voicemail primary action to call log.

+ Add voicemail primary action button, which expands the call log
and plays immediately when clicked.
+ Pass expand/collapse listener into the view holder. This is
necessary because it needs to be triggered when the "play" primary
action is clicked so that the CallLogAdapter correctly registers
what has been added and binded.
+ Update primary action button state when showing or hiding actions,
so the visibility of the voicemail play button is managed properly.
+ Ensure voicemail playback state is consistent between multiple
call log items when the user initiates a collapse or expand. Add
reset function to help manage this.
+ With the reset, protect against the possibility of functions in
the presenter being called when no voicemail playback view is set.
