MainView: fix missing active focus overlay for some items
There are some items that do not have an active focus overlay, which include:
- The advancedAccountSettings page in wizard view: active focus is lost when the Customize button is opened.
- The welcomeview in settings: the JamiIdentifier present in the welcomeView takes the active focus even if the settings page is loaded.
- The callview: the active focus is only taken by the comboBox.
