When entering the URL in the mobile app, if you include the team name in the URL, it will return an error.

For example, http://test.mattermost.com/mytest will return an error, as it only recognizes the server URL and will only accept http://test.mattermost.com.

The app should either directly redirect the user to the relevant team after logging in, or recognize the server URL regardless of the team URL and log the user into the default team.
