Bug 31664: Display pending transfer information on details page

Bug 31664: Display pending transfer information on details page

If a transfer is requested, but not sent, we should display this information on biblio details for staff

This patch also removes nocancel parameter that was not used, passes transfer object directly to template

To test
1 - Manually transfer an item
2 - Note the item shows in transit on details page
3 - Remove the datesent to emulate a pending transfer
    UPDATE branchtransfers SET datesent = NULL itemnumber=1;
4 - View details page - no info on transfer
5 - Apply patch
6 - Item shows 'Transit pending'
