Subject: [PATCH] fix: refreshing a new chat with Landing Page Mode set to Chat
 no longer throws a TypeError (#32510)

With Settings > Interface > Landing Page Mode set to Chat, the new chat
page renders the message list, so the block that reveals a message picked
from search ran there too. With no chat open, chat?.id and
$page.params.id are both undefined, the guard passed, and chat.id threw
"can't access property 'id'" on every refresh.

Require a chat before comparing its id with the page's.
