Fix install-package-tests random build failures

[danielbachhuber]

Builds fail quite frequently with this error:

> install-package-tests
Warning: arning] Using a password on the command line interface can be insecure.
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:32768' (111)

Script install-package-tests handling the prepare-tests event returned with error code 1

Done is:

• Builds no longer randomly fail with this error.

Here's a job where mysql never became available: https://github.com/wp-cli/automated-tests/actions/runs/4683019581/jobs/8297593809

mysql said it was ready though:

LIES

@wp-cli/committers Automated tests seem to be passing more reliably now with #167 and #168

@danielbachhuber Please re-enable testing workflow in automated-testing repository.

@wojsmol Ah, the warning message at the top that I just looked past? 😁 I clicked the button.
