OPENJPA-2443 : Fix SingleFieldManager to not check for null values for IDENTITY
generated fields when flushing.
> InvalidStateException while merging a new Entity with a GeneratedValue id
> -------------------------------------------------------------------------

>
> This problem only happens if you have an Entity with a Generated id that also
> has the annotation @Basic(optional = false). If you create a new Entity and
> then try to persist it via EntityManager.merge(...) call, you'll get the
> following stack :
> <openjpa-0.0.0-rnull fatal user error>
> org.apache.openjpa.persistence.InvalidStateException: The field "id" of
> instance
> "org.apache.openjpa.persistence.jdbc.auto.AutoIncrementEntity@99883308"
> contained a null value; the metadata for this field specifies that nulls are
> illegal.
