Add state loggingIn to MatrixChat to fix flashing login

To prevent the login screen from flashing when refreshing the app, use some state to indicate that a login is in progress, and OR that with the existing `loading` boolean to show the `<Spinner>` instead of the default `<Login>`.

This might be too invasive, and a default spinner may be better.
