Bug 9806 : QA Followup - use template plugin for branch names

With this followup, instead of passing the real names of the branches to template file, only the branchcodes are passed.
The branchcodes are translated into branchnames in template file, using the KohaBranchName template plugin.

To test :
do the same test as for main patch :
1) make some basketgroups with 0, 1, 2 baskets
2) make some basketgroups with different billing and deliveryplace
3) check the list of open and closed basketgroups
4) check action buttons are working like before
