Move VM playback from details to call log.

- Delete voicemail playback in the CallDetailActivity.
+ Add voicemail playback to the call log list items.
+ Move the VoicemailPlaybackPresenter to the CallLogFragment.
+ Fix some retaining state for both call log (expanded items), and
preserve rotation/state functionality for voicemail playback. This
included some changes to the Presenter logic.
+ Fix some tests.
