invalidate startline and bottom_startline when hidden

Browse source 
this was overlooked when adding hidden line support. if the lines are
removed, Irssi has to update the startline. It does that by "scrolling"
the lines to the proper place. The scroll function was adjusted to
calculate 0 for hidden lines, thus it would miss them.
