Shuffle history should not reset completely when the collection changes

[icidasset]

Currently when you enable shuffle and the collection changes, it will forget all the tracks you've already played, so you may hear the same track again. This should not be the case.

Notes:

• A collection changes when: search keywords change, processing added/removed tracks, selected/deselected playlist, etc.
• It does not reset your "queue history", just your "shuffle history"

Should also consider keeping track of the history when closing the app.
