Bug 13741: "No fund found" is not translatable

Bug 13741: "No fund found" is not translatable

The string "No fund found" on the funds overview page is
not translatable.

To test:
- Create a new budget
- Check for the string on the funds page of the new budget
- Run an update on one of the po file sets
    cd misc/translator
    perl translate update <langcode>
- Verify that the string now appars in the po file for staff
- Verify the page still looks the same as before the patch
