[Cog 3357] Clear playlist on start, also status bug

[twoco]

Describe
When the app starts, the playlist should be cleared. Add an options if you want to keep this. I want to start with a new playlist, when starting the app. Don't remember anything. The option clear and play, is a workaround, but what if I want to enqueue it, but only clear once the app started. And maybe if played the same file, remove the first entry (duplicate). Btw. I don't want any disk writes when open files. I don't want to remember the playlist unless I save it.

Also, the last played song in playlist shows status "play" (icon) when starting a new file by double click in Finder. Results in two entries have the play icon.

I also noticed that the play/pause button sometimes hangs in pause state, even no song is playing.

To Reproduce

1. Start a song by double click in Finder.
2. See the playlist from last session is present.
3. See that the last played song also have the play icon (2 entries have it)

Expected behavior
Clean start in app. The playlist should not be stored. This could be an option, since users might want both behaviors.
