function PhpUnitCliTest::testPhpUnitListTests

Ensure that the test suites are able to discover tests without incident.

Generate the list of tests for all the tests that PHPUnit can discover. The goal here is to successfully generate the list, without any duplicate namespace errors, deprecation errors or so forth. This keeps us from committing tests which don't break under run-tests.sh, but do break under the PHPUnit CLI test runner tool.
