Robin Gareus e344d379d2 update semantics of PBD::remove_directory()
Remove the directory recursively including itself. The function
is used in two places only:

* LV2Plugin::add_state() -- no change, remove tmp. state
* Session::save_as()  -- on error, remove target

In both cases removing the folder itself is correct.
