[RotationShimController] fix: rotate on short paths (#4716)

Add header data to goal for short paths.

Commit d8ae3c1 added the possibility to
the rotation shim controller to rotate towards the goal when the goal
was closer that the `forward_sampling_distance`. This feature was not
fully working as the goal was missing proper header data, causing the
rotation shim to give back control to the main controller.
