AppCheck and Auth cause LogOut race condition on page refresh

[ldrummond]

Unfortunately I don't have time currently to reproduce and PR the bug, but I wanted to share to in case anyone runs into a similar issue.

If you are using AppCheck for Auth with ReCaptcha, and are using default persistence state of Auth (local), you may run into this issue. If you log in, then refresh the page, Auth resolves before AppCheck (even if you are using subscribeManually) and logs the user out for invalid ReCaptcha token.

Temporary fix; use "lazy" modules and await loading of AppCheck before loading Auth.
