Message:

see #7427 - remove the tile.loadPlaceholderFromCache mechanism from AbstractTileSourceLayer

There are 2 systems to display replacement tiles from other zoom levels, when the current
tile is not available (yet). This commit turns off one of these systems and relies fully on
the code in AbstractTileSourceLayer.drawInViewArea / paintTileImages.
