[FIX] hr_expense: AccessError on product
[FIX] hr_expense: AccessError on product

- Install hr_expense and stock.
- Add enough products which can be expensed so that a 'Search More...'
  option is proposed.
- Restrict the rights of a user U to 'Employee' only.
- As U, create an expense, and click on the 'Search More...' option when
choosing the product

An AccessError is raised on `stock.move`.

The error is due to fields `qty_available` and `virtual_quantity`.

These fields are not necessary in that context, so we define a specific
tree view for this use case.
