Bug 15036: Do not overwrite complete status in basket ops

Bug 15036: Do not overwrite complete status in basket ops

Reopening or closing a basket should preserve the completed
status for receipted orders.

This patch excludes orderlines with the completed status
from having their status rewritten as a result of the
change in basket status

Made the subroutines involved more efficient by removing an
unnecessary loop and by not fetching a large amount of
superfluous data
