Katrin Fischer 883bc625b2 Bug 5445: Nicer breadcrumbs when ordering from different sources 
Replaces previous patch. Also fixes ordering from existing records.

While it was possible to go back to vendor and basket page when ordering
from a new suggestion the other odering options missed those 'crumbs'.

This patch makes the breadcrumbs for all orderings options consistent and
makes it possible to navigate back to the vendor or basket from all
pages.

- from existing record
- from staged record
- from external source
- from empty record
