Bug 27137: Correctly show biblio title after successfully moving item

Bug 27137: Correctly show biblio title after successfully moving item

In Bug 11529 we changed the variable that was passed to the template but
missed updating the template.

This patch ensures we correctly access the variable to show the title of
the biblio.

To test:
1) Create two biblios (Biblio A and Biblio B)
2) Add an item to Biblio A (Item A)
3) Go to Biblio B
4) In the cataloguing toolbar, click Edit, then Attach item
5) Enter the barcode for Item A and submit
6) Notice the item has successfully moved by Biblio B's title does not
show
7) Apply patch
8) Go to Biblio A
9) In the cataloguing toolbar, click Edit, then Attach item
10) Enter the barcode for Item A and submit
11) Confirm Biblio A's title shows correctly
