Avoid Access Error when search with suspend security.

The Odoo `_search` function performs a  `sudo` on the first line of its
implementation, causing that the uid's wrapper (class BaseSuspendSecurityUid) is lost.

This is evidenced when a function with suspend security is called and in
its implementation needs the values ​​of a 'one2many' field (it does a
`search` in another model without reading access) an Access Error is raised.
