DDC-3067: [GH-999] DDC-3065 null value in in criteria support

Jira issue originally created by user @doctrinebot:

This issue is created automatically through a Github pull request on behalf of Ocramius:

Url: #999

Message:

See DDC-3065 (http://www.doctrine-project.org/jira/browse/[DDC-3065](http://www.doctrine-project.org/jira/browse/DDC-3065))

This MAY be a breakage, since the following API now works as expected:

$repository->findBy(['fieldName' => [null]]);
$repository->findBy(['fieldName' => [123, null]]);

Where before, null was just ignored

[doctrinebot]

• is required for DDC-3065: Generated 'IN' clause doesn't handle 'null' values (needs to add 'IS NULL' check)
