Clears any currently stored token. The next time gmailr needs a token, the token acquisition process starts over, with a fresh call to gm_auth() and, therefore, internally, a call to gargle::token_fetch(). Unlike some other packages that use gargle, gmailr is not usable in a de-authorized state. Therefore, calling gm_deauth() only clears the token, i.e. it does NOT imply that subsequent requests are made with an API key in lieu of a token.
