Use |last_timestamp_offset_|, passed by reference, and test that it is
updated/used correctly (along with append_window start/end) by Abort()?

Updated to use last_timestamp_offset_.
However, MockMediaSource::AppendData does not seem correct in that case: it does
not use the |last_timestamp_offset_|. So 2 consecutive AppendData would possibly
not give the correct result.
