Does this fix the Valgrind errors in https://github.com/coin-or/SHOT/pull/171/files/db906f48a5086fcf698292d83133ff52e44c16e8#r1352778767 @svigerske?

The title of the pull request is a bit confusing, though. What the PR reenables is that you set values for the (primal) starting point of Ipopt. Without it, Ipopt would start from random values given by uninitialized memory. A warmstart would require values for the dual variables. You didn't enable this option in Ipopt, so not providing them is correct.
