[FIX] portal: mail access right test is not totally accurate

The access right test expect an exception
to be raised when accessing any of the
followers, but this is not 100% correct,
as the test user (Chell) should be able to
read her own record.
This worked by chance because the ORM
prefetching was triggering an access error
whenever any follower was accessed, but
this was a bug, now fixed in server at
