Progress Hud is showing on the login page when the app is opened

[tszkanlo]

The progress hud in UserQueryViewController inherited from SKYChatParticipantListViewController -> viewWillAppear() -> performUserQuery()

The login page is now loaded after the RootViewController (tab bar controller) with UserQueryViewController as root controller. So the progress hud will be always here when login page is loaded.

For example, when the server is slept, the progress hud will be shown on the login page for a while before error is returned to dismiss the progress hud.

Solution:

• dismiss the progress hud in the loginviewcontroller
• restructure the login flow for the whole demo
• set time out for the progress hud in uikit
