Bug 21260: Move the count before the callnumbers

Bug 21260: Move the count before the callnumbers

The current display is a bit confusing [Call number: A](2) seems
to indicate that we have two call numbers A. But what it means here,
is: we have two items and we list only one, being A.

So, we'd better do something like:
    Items available for loan: Centerville (2) [Call number: A, ..]
Which says we have two items at Centerville, listing only one (A),
but indicating with the two dots that there are more.

Test plan:
Pick a biblio with multiple available items at a branch.
Include it in a search and check results display.
Test the same but with only one branch in Koha.
