Uninstall does not remove db tables

after drush pm-uninstall I still see the wsclient tables in the database. When re-enabling you will see error that table(s) already exist(s).

The work around can be hazardous! Be careful to first do the un-install operation on all active wsclient modules before you manually remove the tables. If you forget to do that, your site will break and you can only gain back control by manually restoring the wsclient tables.
