Subject: [PATCH] DoctrinePresenceVerifier->getCount() returning null

When using the unique validation rule `DoctrinePresenceVerifier->getCount()` was returning null because the scalar result wasn't been added to the result set.

Also noticed that an error would occur in `getMultiCount()` as the `count()` method isn't available on `ResultSetMapping`.
