Fix #21462

@bruestel : with that change, that works well but I have noticed two points that could be maybe checked/improved:

• The refresh is done in 2 steps/messages. First step is setting one unique temperature as option (probably because access is ready only) and just after there is a message leading to a proper setting of options and temperature value. I noticed that for the first step, this is not the new program default temperature but the previous program selected temperature.
• For very particular programs (like drum cleaning), a temperature is kept while on the washer panel there is no temperature. In this case, we should probably have an empty option list (or maybe "auto" like for certain other programs).
