Address issue #1 and issue #3 of the group test failures.

See Kent's documentation "Designed to Fail Tests and Issues".
(A) Fix for issue #1: HDassert the < and = cases between old and new
entry length.  John will take care of the > case.
(B) Fix for issue #3:  set the cache copy of page_size again if different
    from f->shared->fs_page_size.
