Once we log an exception via next activity in a production, we search moves that have been updated uphill to write the useful information about the change. The issue is by default, the key 'move_orig_id' is searched while some moves could be linked with 'created_purchase_line_id' key.
This commit avoid mapping 'move_orig_id' on empty recordset and so avoid a traceback.
