No check if class instance still exists in handleRecordingDuration

Lines 217 to 221 in 3585e67

	function handleRecordingDuration(counter) {
	counter = counter || 0;
	counter++;
	if (self.blob && self.blob.size) {

There is no check if self still exists when the timeout ends.
That causes an issue in my react app: when the component is unmounted before the recording is stopped, an error occurs saying Cannot read property 'blob' of null.
