[FIX] sale_stock_operating_unit: Reverted change in onchange_team_id

[baguenth]

Hey @AaronHForgeFlow,

in the migration of this module to v16.0 I think there was a mistake: https://github.com/OCA/operating-unit/pull/797

• The obvious issue is, that the function onchange_team_id was just converted from onchange to compute, without adding a for loop. This will break, if we have to compute for multiple sale orders.
• Anyway, I am not sure if we should have changed it to compute in the first place. Actually the functionality should still be given by using the onchange method. We do the same in sale_operating_unit https://github.com/OCA/operating-unit/blob/16.0/sale_operating_unit/models/sale_order.py#L28.

Hey @alan196 and @Chionne27,

this is maybe also interesting for you, since you have been involved in https://github.com/OCA/operating-unit/pull/797.
