EZP-23643: Search without permissions throws UnauthorizedException

https://jira.ez.no/browse/EZP-23643

After refactoring of SearchService for performance in 5.3.3, turning on permission filtering via $filterOnUserPermissions now throws UnauthorizedException because of $contentService->loadContent() use.

The reason this was not caught was because the integration tests testing this has been disabled for a long time (since search was moved from Content Service, so pre 5.0). Found when fixing skipped tests in first commit here.
yes, forgot to change the description after changing the query to be more simple, the ones I removed in the diff was failing. However either wrong use of `Criterion\Field`, or something wrong with it, which means we should deal with that separately, ref:
```php
            array(
                new Criterion\Field( 'name', Criterion\Operator::LIKE, 'Administrator users' )
            )
// And 
            array(
                new Criterion\Field( 'title', Criterion\Operator::LIKE, '*eZ Publish*' )
            )
```
