PersistentCollection::matching() always returns empty collection, when passed criteria's expression is created using ExpressionBuilder::isNull()

This happens because expression created by ExpressionBuilder::isNull() is wrongly translated to SQL using '=' operator instead of 'IS NULL'.

If the collection is already loaded, result is as expected.
