Before this commit, when hr was installed and Demo clicks on avatar
of Mitchell Admin, open chat failed due to access right exception.
This happens because open chat works only with internal users, and
when we don't know whether the partner has an internal user, we have
to check whether there's a user linked to this partner.
Doing `searchRead()` without passing any field triggers this missing
access right for some reasons.
Only the knowledge of an existing `userId` is enough, so we
can actually just make a `search()` to get the user id. This won't
trigger the access right exception while giving the user id of
the partner if this exists, thus proceeding with open chat request.
