The domain for the analytic account in the `reconcile with writeoff` wizard
should be based on the `type` field, which must be `view`,
not on the `parent_id` field, as it's done everywhere else
(e.g. in the supplier invoice form).

`[('parent_id', '!=', False)]`
and
`[('type', '!=', 'view')]`
is almost the same, but the second domain is more appropriate.

Closes #4562
