Use disconnect() because close() doesn't exist

SmallWebRTCConnection doesn't have a `close()`. There's a `_close()` but I assume that's private due to its naming. The closest function that uses `_close()` is `disconnect()`. I assume then, that the intended resource freeing function call should be to `disconnect()`.
