patch

The audio element's life time should synchronize with document's life time.

V8 has following problem.
1. V8 GC removes an audio element at any time.

r45537 made JS GC collect an audio element created JavaScript only if (!audio.paused()).
The condition causes 2 bugs.
1. LEAK : If playing the audio element and navigating another page,
audio.paused() returns "false".
2. GC sweeps the audio element at any time, not during playing. It makes web
developers confused because they can not play audio after GC.
