Some UI tweaks for New App Layout

[gileluard]

Your use case

As per our discussion with @amshakal here are some tweaks we could make:

• Display create space menu item only if the user has at least one space
• Add a cancel button to the "My spaces" screen
• Change the "Create" button style of the "My spaces" screen to fit the built-in done button style
• Reduce the size of the avatar in the All chats screen to match with the size of the right button

Have you considered any alternatives?
