Subject: [PATCH] fix: ignore special chats when calculating similar chats

The second SQL statement calculating chat size
was already fixed in f656cb29be8ac23f854859c13e70109009441f63,
but more important statement calculating member list intersection
was overlooked.
As a result, trash chat with members added there due to former bugs
could still appear in similar chats.
