Fix deployment and tests (correct URIs, plugins)

- install also the Sahara plugins. The existing variable sahara_plugin_base
  is now used also for the list of installed plugins, in addition to
  the list of loaded plugins.
  The default set includes now all the available plugins.
- fix the URIs used by role tests. They will eventually go away
  in favor of the integrated tests, but they are needed right now.
