Compare Forecasts without fake data

[utzy]

I use the compare forecast view to see differences between forecasts and I love this feature!

Since adding the AROME and ALADIN models this view has become confusing though.
For these models you show mostly ECMWF, which can give the imprssion that all forecasts are aligned.

Please do not repeat ECMWF model. Just do the same as for ICON and meteoblue...just show nothing. That would be most helpful in this view, I think.
