Gooseberry: Fix for flickering grass

The issue was caused by memory optimization marking particle system to recalc,
and because of the way how particle flags works it was possible that it'll
cause particle's re-distribution. Now this memory optimization will act the
same as loading the file.

Would need to review if this fix is to go to master/cycles_memory branches
but for now it'll be cool to figure out what to do with the farm.
