Add some more history to the svn_repos_revision_changed() tests, and
fix a little buglet in the new fs history code that doing so revealed.

* subversion/tests/libsvn_repos/repos-test.c
  (revisions_changed): Add some quirky copies and moves to the
    revision set here, and re-org the test data a bit for readability.

* subversion/libsvn_fs/tree.c
  (txn_body_history_prev): Pass NULL for the end_copy_id parameter of
    find_youngest_copy() for now.  This parameter may wind up getting
    trashed in the future as unused, but I need to think through that
    a bit more.
