PHPUnit doesn't report all risky tests

[PVince81]

@DeepDiver1975 see the two test classes CustomGroupsBackendTest and CustomGroupsManagerTest.

Each class has one empty test class.

When you run the tests with make test-php (or cd tests/unit; phpunit), it will only report one risky test:

1) OCA\CustomGroups\Tests\unit\CustomGroupsManagerTest::testEmpty
This test did not perform any assertions

/home/vincent/.composer/vendor/phpunit/phpunit/src/TextUI/Command.php:149
/home/vincent/.composer/vendor/phpunit/phpunit/src/TextUI/Command.php:100

OK, but incomplete, skipped, or risky tests!
Tests: 24, Assertions: 104, Risky: 1.

For some reason any risky tests inside of the first class alphabetically CustomGroupsBackendTest are ignored.

(ignore the failing test, you can make it disappear by checking out the branch group-displaynames in core)

@DeepDiver1975 not needed, I'd rather have the core branch merged soon...

Okay, I pushed the setting about empty tests to the app branch: #1

Thanks!
