mysqltest regex replace results in incorrect result

Details

    Description

      From https://travis-ci.org/MariaDB/server/jobs/238967452

      As seen with the : plugins.server_audit and plugins.thread_pool_server_audit tests

      Setting a large hostname like travis (testing-docker-99f46c25-f6c4-4465-bc49-ee78d188e37c) is sufficient to trigger test. A smaller test hostname of
      testing-docker-99f46c25 passes.

      The regexs are right using [^,]* as the host match which should match the hostname. Though it escapes for ',' I don't think escaping is needed (and it doesn't affect result removing escapes).

      related to c91ecf9e9bebf3cf2dafbd3193de4df94be09870 ?

      Testable locally by changing hostname to a name above with hostname command.
