Allow createBuffer to support rates from 3-192 kHz.

The spec requires a minimum range of 22.05-96 kHz. (http://webaudio.github.io/web-audio-api/#widl-AudioContext-createBuffer-AudioBuffer-unsigned-long-numberOfChannels-unsigned-long-length-float-sampleRate)

Add two new tests to verify that 3 kHz and 192 kHz are allowed and
update expected test results for allowed range.
