Bug 779715. Part 7: Update test_streams_element_capture_reset.html to test new functionality. r=cpearce test_streams_element_capture_reset.html is updated to test that mozCaptureStreamUntilEnded actually stops capturing when the stream ends. It also tests that seeking and reloading the media resource keep feeding a mozCaptureStream stream, and feed the right amount of data.
