Bug 34086: Show location on detail page when there is no permenant location

To test:
1. Have some items without a permanent location.
2. Go to the staff detail page.
3. In the 'Home library' column notice the span .shelvingloc is empty.
4. Add a permanent location, now the shelvingloc is populated
5. Apply patch
6. The location should now show even when there is no permenant location.
