Split the move-update handling for deletes in two parts: one for nodes that
are really in the working copy (=not shadowed) and one for all deletes.

* subversion/libsvn_wc/wc_db_update_move.c
  (tc_editor_delete): Extract the code for shadowed nodes into...
  (delete_move_leaf): ... this new function which is now called from the
    caller. This matches how the alter functions are implemented.

  (update_moved_away_node): Update caller.
