Steps to reproduce:
1. Create a folder in "Shared files" called "hubbabubba".
2. Add the "Saved searches" dashlet to your user dashboard.
3. Change the search term to "hubbabubba".
The dashlet will display "Loading..." and never return any results.
A brief look at the code shows that the /components/dashlets/saved-search.js code in function "renderCellDescription" expects that the search result item has a "site" property. The results returned by /alfresco/templates/webscripts/org/alfresco/slingshot/search/search.get.js do not set this property if the result is not located on a site.
