Prefetching doesn't work with prefetched subentity
--------------------------------------------------

                 Key: CAY-1250
                 URL: https://issues.apache.org/jira/browse/CAY-1250
             Project: Cayenne
          Issue Type: Bug
          Components: Cayenne Core Library
    Affects Versions: 3.0M6, 2.0 branch
            Reporter: Donald Vrakking


Two entities;  A->B in a n:1 relation, B has a subentity. When prefetching B, the toOneFault
on A isn't updated with the prefetched B. When B is accessed from A, an additional query is
still executed to get B.

It makes no difference if A has subentities or not.

This occurs in 2.0.4 with a disjoint and joint prefetch. With 3.0M6 it only occurs when using
a disjoint prefetch.
