This global from MediaWiki was removed in 854a462 in 2016 but we didn't
clean up after it at the time.

It's shorter, and allows us to take advantage of any future improvements
to setGroupPermissions, such as automatically resetting affected
services.

The test suite set $wgTitleBlacklistSources with a fixture source of
directories. Unfortunately when running tests from MediaWiki core the
TitleBlacklist has already been set with empty value and thus setting
the global is a noop.
That later causes a test to fail because the blacklist is emtpy.
Add TitleBlacklistTest::destroySingleton() so a test can reset the
singleton when changing $wgTitleBlacklistSources.
Since that is solely for testing, throw an exception unless we had
MW_PHPUNIT_TEST defined.
