Fix tests, QuerySubscriber

* Fixed vendor.php (used actual 2.3), because old versions has some
WhereInWalker BC breaks
* Updated doctrine -> updated BaseTestCaseORM for properly Configuration
mocking
* Added AsIsHydrator for getting results in QuerySubscriber
* ORM tests mostly passed
(shouldNotBeAbleToCountCompositeKeyOnByCountQueryWalker failed)

So i hope it will fix:
