do not display user info if access token is expired

[zugdev]

Currently in authentication, we have two different conditions to show user GitHub info and the login button.

work.ubq.fi/src/home/authentication.ts

Lines 14 to 23 in bd41261

	const gitHubUser: null | GitHubUser = await getGitHubUser();
	if (gitHubUser) {
	await trackReferralCode();
	await displayGitHubUserInformation(gitHubUser);
	}
	const accessToken = await getGitHubAccessToken();
	if (!accessToken) {
	renderGitHubLoginButton();
	}
	}

This leads to a scenario where both can be shown at the same time or none is shown:
