When printing labels in a `ready` picking, if no quantities are set it
will only print the reserved quantities as labels.
Then, if a product has no reserved quantity, it will not have any
move_lines. Which means its initial demand won't be able to be fetched,
and the default behavior will be used, which is to print a single label.
By giving the moves instead of the move_lines to the wizard, we allow to
fetch for moves that have no reservation and print labels correctly
using their initial demand if no reservation is found.
The standard behavior once quantities are set remains untouched.
