Bug 27353: Set X-Base-Total-Count header for REST API

Bug 27353: Set X-Base-Total-Count header for REST API

We already set X-Total-Count to the total number of filtered rows,
but we don't have the total number of non-filtered rows.

Test plan:
This is easy to test on top of bug 27352 or bug 27251, apply them if not
pushed yet.
1. Create 40 items with public notes = "xxx" for biblionumber=4
then, using Postman (or whatever you prefer):
http://kohadev-intra.mydnsname.org:8081/api/v1/biblios/4/items?_page=1&_per_page=20&q=[{"me.public_notes"%3A{"like"%3A"%25x%25"}}]&_match=contains
Check the headers and confirm you see X-Total-Count=40 and
X-Base-Total-Count=44

2. go to /cgi-bin/koha/tools/quotes.pl
You see "Showing 1 to 20 of 28 entries"
Search "he"
Showing 1 to 20 of 22 entries (filtered from 28 total entries)
