remove (hopefully unused) code regarding GUEST and USER_FOLLOWING_LINK

I can't reproduce or think of scenarios when this code was used. because bottom dialog is replaced it wouldn't work anymore anyway.
If there appear scenarios when the code would have executed, it should be fixed similar like ConversationsListBottomDialog was implemented.
