Since Chrome 120 (specifically Chromium build 1208985), an empty message is received from the CDT at the end of a test run, which obviously cannot be parsed as JSON. This is due to a fix made in Chromium [1] where ChromeDriver didn't send the CLOSE frame in response to the CLOSE frame sent by the client. The websocket-client library we use to talk with the CDT interprets this frame as a empty string when receiving message (cf. in `_core.py` [2]). As we don't need to interpret more complex low-level messages, this commit simply skips the empty message (which was already implicitly done in 15.0 [3]).
