shopfloor: checkout fix line done with zero qty

Follwing this change

    OCA@b2ce1bd

Multiple lines are displayed in the `select_package` state.
Some could have the quantity done set to zero. In that case the lines
should not be set has checkout done.

When putting lines in a package it is already handled by
`_filter_lines_to_pack`
