Fix: memory leak after type conversion in geometry nodes group

The leak happened when two things were true:
* Inside of a node group a socket is linked to a Group Input that has
  a different type.
* The corresponding input on the parent Group node is not linked.

The conversion happened correctly, but the original value wasn't
destructed.
