Don't zoom when there's only one pane (#7273)

Browse source 
This is a minor fix from #6989. If there's only one pane in the
Terminal, then we'd still "zoom" it and give it a border, but all the
borders would be black. 

A single pane is already "zoomed", so it doesn't really make sense to
try and zoom if there's only one.
