[FIX] mail: prevent use of private addresses for followers, recipients,...

- Connect with Admin
- Go to Contacts, edit himself by adding a Private Address
- Create an Internal User without "Access to Private Addresses" right (i.e. User X)
- Go to any app implementing chatter (i.e. Sales)
- Create a SO
- Add the created Private Address as follower
- Make sure User X can access the record (i.e. Sales: Administrator)
- Connect with User X and open the SO
An Access Error is raised while trying to fetch data about the followers.

This commit prevents to:
- add a private address as follower of a record
- add a private address as Recipient in full composer
- propose private addresses when adding a mention to a partner
