[UPDATE][SHELL] Make less clear screen on start-up

If you don't have this option, less will just start outputting from
wherever your cursor was (so the line where you were writing your
command), but any movement would make it snap to the top of the
terminal.

This makes it clear the screen before doing its first draw, making the
output systematically start from the top.
