UnhandledPromiseRejectionWarning when making request with expired token and no callback/refresh supplied

Hey,

I noticed that as of version 4.0.0 I no longer receive an error message alerting that the access token has expired when a request is made with an expired access token (not using the newly implemented token refresh functionality).

Instead I receive two UnhandledPromiseRejectionWarnings: My Code:

var YahooFantasy = require('yahoo-fantasy');
var yf = new YahooFantasy(
  clientKey,
  clientSecret,
);
yf.setUserToken(
  accessToken
);

// Game
games = async () => {
  try{
    const data = await yf.user.games()
    console.log(data)
  } catch (err){
    console.log(err)
  }
}
games();

The error

(node:8892) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

I have run the following code to get more info:

process.on('unhandledRejection', (reason, p) => {
  console.log('Unhandled Rejection at: Promise', p, 'reason:', reason);
  // application specific logging, throwing an error, or other logic here
});

And receive this:
