    appDisplay: Hide frequent view when app monitoring is disabled
    
    Currently we stop monitoring application usage when disabling the
    'enable-app-monitoring' setting, but we still expose previously
    gathered data in the app picker's frequent view. This is not what
    users should expect, so hide the view in that case.
