Bug 28202: Pickup libraries must be sorted by name when placing hold

When placing hold, the pickup libraries are not sorted by name but by code.

You can see in other places : pickup_locations() calls
Koha::Libraries->search with { order_by => ['branchname'] }

Test plan :
1) Go to staff interface
2) Create a new libary with code 'AAA' and name 'ZZZ'.
2) Select a record
3) Begin placing hold
4) Look at list in "Pickup at:"
=> Without patch library 'ZZZ' is first
=> With patch library 'ZZZ' is last
