[FIX] google_account: error type on wrong request

Configure google to be synchronized with Odoo, create a contact with a
wrong email address (I used `foo@.test.`), create an event in the
calendar, add the contact as attendee, sync with google. Traceback.

The traceback is a `request.exception.HTTPError` reraise by
`_do_request` in the `google.service` model on several HTTP errors, 400
amoung them. The real error is "Invalid attendee email." but the
information is lost in the error message.

The error hanlding has been rethink so it raise a user friendly error
via the UserError modal with just the error message sent by the Google
API. The logged error has been rethink to pretty print both the request
and the response.
