The remove operations for RocksTrieDB are no-op.

Current Behavior

I'm not sure if they were correct, but the remove operations for RocksTrieDB are no-op.

axon/core/executor/src/adapter/trie/db.rs

Lines 117 to 123 in 1c6af01

	fn remove(&self, _key: &[u8]) -> Result<(), io::Error> {
	Ok(())
	}
	fn remove_batch(&self, _keys: &[Vec<u8>]) -> Result<(), io::Error> {
	Ok(())
	}

Expected Behavior

I thought these two operations should be real operations.

Anything else?

When I debug #1439, I found these two remove operation were called.

But these are not reason for that issue.

The remove operation should be a no-op. If it actually deletes db kv, data under previous roots may become unavailable.
