[FIX] account, sale: avoid error when internal user (no accounting

permissions) edit information at /my/account

Issue:
Internal user cannot edit their information (email, street,...) at
portal without permissions in the accounting

Analyze:
Because the method `can_edit_vat` has a search from the account.move
model, it causes an error

Fix:
Use sudo to avoid error when searching
