Amplify-js: UI Components: session not persisted after sign up

[amhinson]

Describe the bug
When using the new <amplify-authenticator> in Vue, after I sign up and enter the confirmation code I can see in the browser that I am automatically signed in. However, after refreshing the page, the auth session didn't persist and I see the sign in screen. Once a sign in again and refresh the page, the session is persisted.

To Reproduce
Steps to reproduce the behavior:

1. Follow quick start setup steps and Vue usage
2. Click "Create Account" and enter in info.
3. Enter confirmation code and click "Confirm"
4. See user as "signed in"
5. Refresh page
6. See login screen again

Expected behavior
User stays signed in after sign up confirmation.
