Resolves: rhbz#1546997 'search not found' at 0,0 when window too narrow

if the statusbar hadn't got space for the initial label, then it doesn't get set a position,
so when later forced visible it draws at 0,0

call Resize on the toolbox to get it to relayout, and while we're at it
set the required size of the label so we might have space for it if that
text is shorter than the original len allocation
