Wrong links after adding/deleting workflow state

[holdenhao]

After a workflow state is added or deleted in the ZMI, the URLs in the workflow page get the wrong path. This affects links to workflow states which is missing the "states" in its path while the transition tab is missing the workflow name in its path.

wrong:
http://localhost:8080/Plone/portal_workflow/my_wflow/test/manage_properties

correct:
http://localhost:8080/Plone/portal_workflow/my_wflow/states/test/manage_properties
