fix(train): only the firmware version the person agreed to is written (ADR 0030, D55)

Browse source 
Relayed by the instance, the version asked again before downloading was written even where it wasn't the one shown and agreed to, and the band recorded as at the agreed one. Another version now writes nothing and is offered instead.
