Write params if system is solved as REDUNDANT_OKAY.

Browse Source 
A system solved as REDUNDANT_OKAY is still solved correctly,
even if the UI would consider this an error, in case that
g->allowRedundant==false. So there's no reason to discard this
solution; we might find it useful if a system loses a degree of
freedom while dragging, or to avoid regeneration after redundant
constraints are allowed.

This commit also reverts commit 3ff236c, as that is not necessary
anymore.
