Bug 19769: 'Pickup library is different' message does not display library branch name when placing hold

When placing a hold for a patron whose pickup library and home library
are different, the message displayed only shows the branch code and not
the branch name.

This patch displays the branch name as well as the branch code.

To test:
1. Search for an item
2. Click 'place hold'
3. Enter patron name/card number for a patron whose home library is
   different to the item's
4. Note the message displayed only shows the branch code but not the
   name
5. Apply Patch
6. Repeat 1-3
7. Message should now also display the branch name
