Don't show list in non-members profile

Hi @maxking,
thanks for exposing the non-member option in postorius. It works as intended, but there is one issue. When I add a user as non-member to a list, that list is going to be shown on the profile of that member (even when it's unadvertised) so that he or she can subscribe to the list or make a subsription request. In my opinion, that list should only be shown in the members profile if he or she is at least a member, but it shouldn't be shown if he or she is a non-member. Alternatively it could be shown without the possibility to subscribe to that list. Thank you!
