Subject: [PATCH] Fix scroll history to down with unread bar.

Regression was introduced in 972b5078f6.

When we show history at a specific message or at unread messages we
need to clear and destroy old showFrom and unreadBar like it is done
in historyLoaded(), otherwise we always scroll to existing unreadBar.
