Topbar title broken for item with default_action

[Anna Wojdel]

If main menu item does not open a new controller, but there is an default action assigned to it, the topbar title is not updated.
It's hard to reproduce as currently all items in main menu just open a new controllers, but it's visible in account creation branch.

Steps to reproduce:
1. In account creation branch go to Settings -> Account Settings
Expected Result:
Title: 'SETTINGS' will be displayed in top left corner
Current Result:
No title visible

2. Go to Music -> Library
3. Go back to main menu
4. Go to Settings -> Account Settings again
Expected Result:
Title 'SETTINGS' will be displayed in top left corner
Current Result:
Displayed title is from previously entered section ('MUSIC')
