[Doctrine] fixed circular reference issue with var_export() and conversions

The Doctrine ORM query cache uses var_export() to make a cache key, and as the WhereBuilder
uses query hints for conversions making it refer to its self. But the WhereBuilder
has a reference to the container and Doctrine this all explodes.

So instead we pass a closure with a reference to the WhereBuilder to the QueryHint.
And that works perfect.

This adds the QueryWhereBuilderHelper for adding the WhereCase to a QueryBuilder object.
There were some issues with making the WhereBuilder compatible with the ORM QueryBuilder, the QueryBuilder has no hints so these need to be passed manually. And I did not feel comfortable with adding two getters for this edge case.

The WhereBuilder is already very coupled so adding two other methods would not contribute to a more clean code base.
