Bug 11027: (follow-up) hide link if no basketgroup and use real branch name

Bug 11027: (follow-up) hide link if no basketgroup and use real branch name

This patch is a answer to remarks made by QA:
- if there is no basketgroup for an order, the basketgroup
  column in lastorders.pl is now blank (instead of parentheses)
- the name of the branch is used instead of its code in the
  branch column

To test: check late orders, included and not included into basketgroup
