fix: make the moxxmpp example work again
Note: to do this, I could not use the ExampleTcpSocketWrapper. If I did, the app crashed on launch. I also added some functionality: the header bar turns green when connected, the FAB says what it does, and you can disconnect. Signed-off-by: Blake Leonard <me@blakes.dev>
