fix sidebar/mail_check painting problem

The bug was triggered when $mail_check was set to 0.

When drawing the status line, the Sidebar lied about its size to
workaround a bug in mutt_FormatString().  Whilst in that function the
Sidebar was redrawn.

The Sidebar got confused over whether it should be visible or not and
promptly vanished.
