Actually walk all dive computers, don't just claim to do so

If the first dive computer had pressure samples, but the second one (and
no higher one) did, then we would draw a flat horizontal line for the tank
pressure graph (but lable it with the correct pressures). This routine
that is hunting for the actual maxima and minima does have to really go
through all dive computers, not just "this one and up".
