fixed some problems of downloaded tab and caches

[twistios]

• also now hidden downloaded songs are now always shown
• downloaded songs are now also removed from Download manager (previously was not so when deleting all via data settings, deleted downloads where still shown as downloaded but are actually not)

[twistios]

Current problems:

• Eye icon is still there for downloads tab
• downloads storage usage does not update after deleting all downloaded songs (if one does not exist the menu first)

downloads storage usage does not update after deleting all downloaded songs (if one does not exist the menu first)

This can be easily fixed, but not fully. Because the "deleted" state does not get reset, so it can happen only once while in that menu

EDIT: ok, I was wrong, it seems to work multiple times.

Another problem is that the number potentially does not update, if it is changed by new data.

Eye problem remains, but otherwise these changes should be ok. Hope it does not break with the other changes.
