Adapter fails if vehicle is configured but currently not reachable/offline

[eviw]

Describe the bug
EVCC adapter stops (yellow) with error "undefined is not a valid state value" after it has identified a vehicle in the config.
The error probably occurs, because the connection to the car is currently broken and no current values can be retrieved.
But evcc is working and running without error. In case car connection is offline, it just takes the latest states it received from the car.

vehicles template mg2mqtt is used with config like this:

`vehicles:

• type: template
  template: mg2mqtt
  title: MG4
  user: [email protected]
  vin: xxxxxxxxxxx
  capacity: 77
  timeout: 1h
  name: mg4 `

Expected behavior
The adapter should treat this as a warning only and should continue reading the charger values. That would allow to still control evcc via iobroker even if the car SOC is not the latest state.
