Apply some query tweaks to make sure the upcoming Sqlite 3.7.16 uses the
right index in these queries, where the view behavior is not strictly defined.

* subversion/libsvn_wc/wc-queries.sql
  (STMT_CACHE_TARGET_PROPS,
   STMT_CACHE_TARGET_PRISTINE_PROPS): Avoid using the NODES_CURRENT view in
     this query as the sqlite optimizer can't always look through views.
     Add an (ignored because this query follows the primary key) order by
     to add another hint to the optimizer to use the right index on NODES.
