Revert 0d3da1343c16e1be6a6e6b78b77cf8b3354afe07
Disabling group -> duplicator dependencies would in theory make caches
more attractive because the invisible objects don't have to be updated
just because of the group.
However, the viewport and render starts to behave unpredictably without
these updates, because the dupli cache relies in many ways on the
objects it is supposed to override.
