Fix setup of second car

[dvx76]

Based on robinostlund/homeassistant-volkswagencarnet#617

See also #276 although the issue initially reported there is unrelated.

I have 2 EVs (Enyaq and Citigo). Recently started having an issue that only one of the cars worked, the other was "Unavailable". Sometimes both were unavailable. This used to work before, this started recently.
I did copy the changed file and both cars work now. Thanks for this, hope this will be in the next release :)
