Without the change python3Packages.websockets fails tests on
machines under load:
python3.9-websockets> ERROR: test_keepalive_ping_with_no_ping_timeout (tests.legacy.test_protocol.ServerTests)
python3.9-websockets> Traceback (most recent call last):
python3.9-websockets> File "/build/source/tests/legacy/test_protocol.py", line 1270, in test_keepalive_ping_with_no_ping_timeout
python3.9-websockets> ping_1_again, ping_2 = tuple(self.protocol.pings)
python3.9-websockets> ValueError: too many values to unpack (expected 2)
The change disables the test.
