ManyToManyRawIdWidget broken after

The ManyToManyRawIdWidget is broken since it subclasses ForeignKeyRawIdWidget and it will do a query to grab its object for display of the object. Since the value for a m2m is a list this will throw a database level exception (at least with PostgreSQL it does). The simple fix is to just ignore the value when it is a list. Noting this problem in this ticket so I don't forget.
