Title: Fix returning to a smart group search after adding an activity.

The previous fix was here: https://github.com/civicrm/civicrm-core/pull/1770

However, this was missing the civicrm/group/search url in the list of possible urls to return to; thus smart groups were still broken for this workflow.
