Update a query to work slightly faster and to reduce the dependency on
explicitly unspecified sqlite behavior.

This fixes 30 op-depth tests when running the tests with our verification
triggers in maintainer mode *combined with*
SVN_SQLITE_REVERSE_UNORDERED_SELECTS.

Note that this problem doesn't affect non maintainer mode behavior, as
we don't rely on the ordering there.

  (STMT_INSERT_DELETE_FROM_NODE_RECURSIVE): Tweak query to force inserting
    the rows in a strict order. Assume that the op-root matches our check.

  (STMT_INSERT_DELETE_LIST): Update to match
    STMT_INSERT_DELETE_FROM_NODE_RECURSIVE, to make sure notifications
    match actual behavior.
