vnc: Fix artifacts in hextile decoding
02c2b87
introduced a regression whereas the foreground color in a hextile
update was not being properly invalidated leading to artifacts.
It's still necessary to explicitly invalidate the foreground color with a
SubrectColoured tile even though we no longer send a foreground color as
part of the tile.
