This (the fatal error) happens because of in ORM/Tools/SetupTest there is a condition in setUp() that marks test as skipped, but tearDown() is being invoked anyway (that is how phpunit works).

So tearDown() should run only in case if setUp() hasn't skipped the test, otherwise tearDown() deletes registered autoloaders

PS: other tests failed because I haven't set up any database
