Bug 19825: Make links to biblios on pending offline circulation page working again

0) Do not apply the patch
1) Have pending offline circulation operations - you can use standalone
application, Firefox add-on or built-in offline circulatin client - it
does not matter in this case
2) Go to Circulation -> pending offline circulation actions
3) You see all barcode in red and without links - even if the item and
biblio existed
4) Apply the patch
5) Repeat 1-3, now you should see the links to biblio on existing items

Note: Don't add non-existent barcodes actions and payment actions unti
bug 19771 is not fixed
