NLA: fix keyframes getting messed up when making strips longer. For drawing

and other operations the nla mapping would be applied to the curves, but not
restored correctly. The unmap function was not the inverse of the map function,
and it's not clear to me it's even possible to make it so due to repeat, so
now the old coordinates are backed up in a list and then restored afterwards.
