Subject: [FIX] web: handle nested x2m default values

A `default_get` for a x2many field can return a new list of commands for one of
its x2many field, like

[[0, 0, {
    'groups_id': [[6, 0, [1, 2, 3]]],
}]]

where [1, 2, 3] is a list of existing ids.

This use case was not correctly handled by the BasicModel because
`_makeDefaultRecord` was not recursive.

Closes #22401
