Reuse old redio buttons

Browse Source 
When a media is changed, normally one would expect to create new radio buttons with video/audio/subtitle tracks names corresponding to current video, but this is inefficient. Destroying objects just to create similiar ones again does take a long time and might lead to memory leaks. That is why a better and faster approach is to simply edit already available objects to match our expectations instead. This commit does just that for tracks radio buttons.
