pwarszawski 39244a88a5 tests: wait for the pressure switches before notching up ...

full_power() notched up as soon as the controlling half had closed its line
contactors. In the ET42 test the locomotive brake is still at about 2.0 bar
then, right at the pressure switch threshold, so whether the second half
starts as well depended on thousandths of a bar in its cylinder: a half whose
switch is on when the controller leaves zero doesn't close its line
contactors until the controller is back at zero. Any change to the air
brakes could tip it either way (with the corrected ESt3 the second half
stayed off and the train reached 88.7 instead of 106 km/h).

The helper now waits, as a driver does, until no pressure switch in the
train cuts the start off.
