While one could get back to an ongoing call on #phosh's lockscreen by swiping
to the right it wasn't clear if there was still a call ongoing. This will be
improved by showing a notification on the lockscreen making it hard to miss (and which we can likely also use to switch between calls once the calls app supports it):

While at that I put notifications and media player widget into the same
scrolled window and have that use more vertical space so things are (hopefully) less clumsy to use.
