[IMP] stock: auto-print reception report labels

Add in feature to allow auto-printing of reception report labels
at picking validation when there are lines assigned in the reception
report (i.e. any MTO linkages/move_dest_ids).

Note that a little fix hack was necessary for this feature (i.e.
override of ir.actions.report to ensure that the doc_ids/docs are
correctly set) since this report was originally designed to be called
ONLY from the JS + using the report link to pass the correct parameters,
which cannot be done in the same way via the standard
ir.actions.report.report_action method

Part of task: 3046178 - general auto-print goal
