[FIX] STOCK: Fixed the warning.

Hello,

Fixed the warning **WARNING: 'tree_view_ref' requires a fully-qualified external id (got: 'view_move_picking_tree' for model stock.move). Please use the complete `module.view_id` form instead.**
 Occuring at  #Sentry  id: ID: 6fec602854a7407f9c8727fce55e7993

Thankz.
