Problem
-------
Sales people can have restriction on partner they can see
Private addresses, multi company, ....
When they convert a lead to opportunity, it's currently possible
that the wizard will find and link a partner that the current user
cannot see.
Solution
--------
Field that are now computed store field, that were previously
normal field with onchange, should not be computed as sudo
to respect the record rule
