Accessing a linked repair record through Helpdesk can lead to a blocking bug where the user is unable to generate a quote through the repair record.

### Description of the issue :

1) When generating a `repair.order` record through a Helpdesk ticket or accessing an existing linked repair order through the smart button, the context key for `default_team_id` will be inherited. In this case referencing the id of the current `helpdesk.team` record.

2) When trying to generate a quote through the repair order, an edge case can happen where a ValidationError is triggered at sale order creation.
```
The operation cannot be completed: another model requires the record being
deleted. If possible, archive it instead.

Model: Sales Order (sale.order)
Constraint: sale_order_team_id_fkey
```
This is due to the fact that the `sales.order` also uses a `default_team_id` context key to designate the default sales team.

If by happen stance, the referenced `id` values does not match an existing `crm.team` record, you will hit the above foreign key constraint blocking the user from generating the quote.

### Proposed fix :

Functionally it makes no sense to pass the `default_team_id` context value from helpdesk to sales order, as both implicitly reference different models and functional entities.

Since the `_prepare_repairs_default_value` was already introduced in https://github.com/odoo/enterprise/commit/edd88ebdcc60b7c4d261bfb8755e910356684a3f to handle the context value preparation when using the repair smart button, the simplest solution is to set the `default_team_id` context key to `False`, thus not passing it later on to the sales order (i.e. the quote will not have a default sales team, but the user can still manually define one)

### How to reproduce:
1) Set up a DB with sales, helpdesk and repairs installed 
2) If using demo data, just create a handful of new helpdesk teams (`helpdesk.team`). The important part is that you have at least one record with an id that will not be present in the `crm.team` table
3) For the helpdesk team matching the above criteria, activate the Repairs option (`use_product_repairs`) in the team configuration 
4) Create a helpdesk ticket for that helpdesk team, create a repair order using the action button, then try using the Create Quotation action button (`action_create_sale_order`)
