Bug 13750: Holds queue - Show branch name instead of branch code

When the holds queue report is limited to one library, it shows
<cound> items found for <branchcode>

With the patch applied, the branch name is shown instead of the code.

To test:
- Go to circulation > Holds queue
- Limit to one branch with holds waiting to be processed
- Confirm the string has changed to show the branch name
