Calling AudioNode constructors should have identical behavior to using create*() function on BaseAudioContext

[Chris Dumez]

Calling AudioNode constructors should have identical behavior than using create*() function on BaseAudioContext. Otherwise, this leads to assertion hits like:

We need to make sure that the AudioContext gets initialized when an AudioNode constructor gets called. We also need to make sure refNode() gets called if necessary.
