[FIX] core,account_sequence: avoid `add_to_compute` no-store no-compute fields

Since https://github.com/odoo/odoo/pull/121355

,
add_to_compute on no-store compute field, lead to recompute the field
at the end of request and it can lead to some non deterministic bug
(compute with a bad context by example).
Avoid to add_to_compute no-store or no-compute fields.
