'fallback' default vehicle (rather than 'fixed' default)

[stefan-3r]

problem
I have two cars, one of them (Smart #1) not getting detected automatically. If I state this car's name as vehicle-parameter in the loadpoint-section, the working automatic detection of my other car is blocked.

the solution I'd like
I think, a fallback_vehicle-parameter in the loadpoint-section could solve it (if you don't load guests' cars too often - like us). The detection algorithm could then try to detect the connected car and then and onley then switch to this default, if the automatic detecttion fails.

(better) alternative
... of course would be the fix of the detection of the Smart #1. But I think there are severe reasons that prevent this - maybe some missing parameters in the hello-smart-api!?
