Fix T38553: Crash load new level; array modifier using curve length 

Since threaded object update we've disabled in-place
curve evaluation (in cases when applying curve modifier
with target curve non-evaluated yet).

This requires game engine to take care of DAG and object
evaluation (currently it's designed to export only objects
it able to render).

This workaround will make sure that curve_cache for curves
is up-to-date.
