Bug 33340: Correct formatting of English 1-page order PDF when it covers multiple pages

If a basket group contains many ordered items then this patchset will
ensure:
 - The page number at the bottom of the first page is not obscured
 - The table of ordered items does not start half way down the second
 page

Test plan:

1) Go to Koha Administration -> Libraries. Ensure Library A has an
address, phone and fax.
2) Go to Koha Administration -> System preferences. Search for
OrderPdfFormat. Set this to English 1-page layout option.
3) Go to Acquisitions. Use an existing vendor or create a new one.
Ensure the vendor has a postal address, phone, fax and accout number.
4) Create a basket for this vendor. Add many orders to this basket, for
example 25 items (this is to make the Order PDF cover multiple pages).
5) Close the basket and add it to a basket group of the same name.
6) Edit the basket group. Add an address in the delivery place, and a
delivery comment. Check the box to close the basket group and Save.
7) Click the button to Export as PDF.
8) View the exported PDF. Confirm the PDF is multiple pages long. If it
is not then re-open the basketgroup and add more orders to the basket
and repeat steps 5, 6, 7 and 8
9) If the PDF is multiple pages long then confirm:
- The page numbers at the bottom of the first page are not obscured by
the order table.
- That the order table starts near the top of the second page, and not
half way down.
10) Reopen the basketgroup. Edit the details and remove the delivery
place text. Re-close the basketgroup.
10) Repeat steps 7 and 8.
