MobileSDK.oauth.authenticate() should always either Resolve or Reject

[jpmonette]

Executing oauth.authenticate() will not resolve or reject if the end-user clicks the Back button in the OAuth flow.

const launchOAuth = async () => {
  try {
    const token = await SDK.oauth.authenticate(); // execution will never go pass this point if end-user clicks Back
    console.log(token);
  } catch (e) {
    console.log(e);
  }
};

Expected

When a user clicks on the Back button, promise should resolve with no token, or throw an error.

Actual

Code hangs at line const token = await SDK.oauth.authenticate();, never continuing execution flow or throwing an error.

From your description, I'm guessing it's an Android issue?

@wmathurin This has been tested on iOS. I don't know about Android.
