No re-use of trajectory node proto in SerializeTrajectoryNodes (#1293) 

When serializing `TrajectoryNode`, the declared proto is currently re-used. This can lead to unexpected behavior, in particular when the serialization of the proto is performed in an external function.

This PR also relates PR #1277 where exactly that problem occurred in the SerializeSubmaps.
