[FIX] base: don't hide internal users behind rules

Example:
  User 1 has access to company A
  User 2 has access to company B
  Customer 1 is shared, has user 2 as their Salesperson
  Try to create a SO for Customer 1 as User 1
      => access rights issue, the quote is trying to set User 2
	 as the salesman of the quote but cannot because of
	base.res_users_rule

This commit makes this flow possible by sharing users
if they're not portal.
