Actually delete the recording from the WebRTC web-audio test.

Found this bug when I saw files were getting uploaded (after landing
chromium:767857), even when the test was succeeding. This is not WAI,
it should only upload when the test fails.

Turns out it's a bug in the test where we missed to delete one file.
