Improve handling of invalid tokens (#53)

* Improve handling of invalid tokens

This integration is currently failing for me due to an invalid grant. Handle this in `async_setup_entry` so that reauth is triggered.

```
DEBUG (MainThread) [homeassistant.helpers.config_entry_oauth2_flow] Token request failed with status=400, body={"reason":"Invalid Token!","error":"invalid_grant"}
```

* Update __init__.py

* Update common.py
