Fix after namespace issue fix.  Because 'action' always exists in a manage_options entry for an item, its existence in the entry is not a reliable indicator that the entry is not the "View" tab.  Since it was tested for by "has_key", the View tab always pointed back to the current page (manage_workspace).  We fix it here by using "get" instead of "has_key".
