TeslaCar object does not have "vehicle_config"

[kbrint]

Background

In alandtse/tesla#860 we noticed that a recent change made it impossible to close the trunk via the API.

Follow-up discussion on the pull request alandtse/tesla#868 shows that the problem is likely in teslajsonpy.

Cause

While debugging, we find that the check for .get("vehicle_config",{}).get("plg") in TeslaCar.powered_lift_gate never returns True. It's because self._car never contains a key for vehicle_config.

I think the problem is that the TeslaCar._car only contains the data from the PRODUCT_LIST query. The data stored in my TeslaCar object has the following keys: dict_keys(['id', 'user_id', 'vehicle_id', 'vin', 'color', 'access_type', 'display_name', 'option_codes', 'cached_data', 'granular_access', 'tokens', 'state', 'in_service', 'id_s', 'calendar_enabled', 'api_version', 'backseat_token', 'backseat_token_updated_at', 'ble_autopair_enrolled', 'command_signing'])

Fix

I think the fix for powered_lift_gate is to look for the vehicle_config in the self._vehicle_data dict.

#463 should fix this.
