1.6 used svn_wc_get_actual_target but the current code no longer calls
that.

When we come to do the sleep for a single target that is not a working
copy root we need to use the parent directory when the target has been
deleted. I'm not sure what criteria we should use:

  - call svn_wc__node_is_not_present to detect status==not-present

  - svn_io_check_path to detect no detect kind==svn_node_none

  - svn_wc__is_wcroot to detect is_wcroot==FALSE

There is a similar problem with

   svn up wc/node

when the update removes 'node' although this case it's only an
inefficiency not a regression.
