Bug 1227320 - Need to wait two TabAttrModified events to ensure soundplaying attribue is updated. r=ehsan

Browse Source 
We need to receive two TabAttrModified events with 'soundplaying'.
The first one comes from nsDocument::OnPageHide, the second one comes
from nsDocument::OnPageShow.
Moreover 'audio-playback' notification is not passed to chrome process on E10S so
we should wait 'audiochannel-activity-normal' instead.
