Expected behaviour

Unwrapped objects should also show up in the objectChanges list

Actual behaviour

Unwrapped objects don't show up

The changes in https://github.com/iotaledger/iota/pull/9534/files might fix it, but needs to be tested. I created this issue here so the indexer can be fixed first on its own without touching the explorer
