UI Fixes and cleanup

[avdept]

This PR includes following fixes

• Fixed stuck cover art in the bottom player. Sorry this is attempt Temp #2 already but hopefully this time I got it sorted.
• Bottom player artist name - artist label is now clickable on desktop only and does not occupy whole width of the row. On mobile - its not clickable and opening "playing now" sheet much easier now.
• AirPlay / streaming - fixed issue with malformed Container param that would prevent airplay from starting in some conditions.
• Library switching - there was a bug which would break UI after library switch and forced users to restart the app. Now its fixed and library switching works as expected
• Library switched on listen page - now there's icon on top right side after sort dropdown which allows you to switch libraries.
