Title: Check if field mapped as sluggable is identifier only in entities, not mapped superclasses.

I'm not sure if this issue affects also older versions, but in master of doctrine extensions and latest doctrine orm, there is issue caused by [https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php#L981], as the mapped super class doesn't have identifier at all, and we are doing check in the changed line.

This affects only scenario when we define the sluggable in mapped superclass.
