Don't focus 1st room when clicking on account bar

When clicking on an account in the top account bar or using the
Keys.Account.(previous/next) keybinds, go to the corresponding
account settings instead of trying to focus the first room of that
account if there is one: user might not want to clear the read marker of
any random room that is out of view and happens to be the first in the
list.
