[IMP] mail: limit cache invalidation when managing messages

This commit proposes to limit cache invalidation at some cases that will
trigger some behavior change when dealing with mail messages :

 * creating messages linked to a document;
 * update model or res_id of a message;
 * updating notifications, as notified people could change some computed
   fields on the record;

This commit also invalidates only mail-related fields as updating messages
should not invalidate other things than some computed fields linked to
mail.
