Message:

Fix and test for ~~DDC-2073~~(http://www.doctrine-project.org/jira/browse/DDC-2073).

Ticket extract:

> 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.
