ExerciseByKey command issue with upgraded keys

[paulbrauner-da]

ExerciseByKey command nodes don't store the upgraded key. This leads to re-intepretation errors.

exerciseCmdKeyUnchanged : Test
exerciseCmdKeyUnchanged = test $ do
  a <- allocateParty "alice"
  cid <- a `submit` createExactCmd (V1.UnchangedKey a 1)
  res <- a `submit` exerciseByKeyExactCmd @V2.UnchangedKey (V2.UnchangedKeyKey a 1) V2.UnchangedKeyCall
  res === "V2"

Still needs to be fixed for 3.x
2.x's solution was a hack, a proper solution is needed for 3.x so we can't just forwardport
