Add card image to the QuickAccessWalletTile.

We fetch the wallet cards on handleUpdateState() of the Tile, if the
card image exists, it will be stored in the QS State and then pass to
the QSTileViewHorizontal so the card image will be presented on the
tile.
The car image won't show on the tile when the user is edittng the tiles.
