Particles: Fixes for synchronization to original

Was missing synchronization of current frame to the original one,
which is one of the issues why point cache does not properly reset
on edits.

Also clear recalc flag on original particle system.

Ideally we need to get rid of recalc on a particle system, since
that is not really covered by tagging system of dependency graph.
