ptyfwd: when leaving a session with tinted background, clear to end of screen

Browse Source 
So if we tint the background of a ptyfwd session with a color and the
session ends, then so far we reset the bg color and clear till the end
of line.

Let's instead clear till the end of the screen. This is nicer since it
means that any follow-up output will not be affected by the changed
background color anymore.
