[Bug] Can't accept self-created offer files

[HarveyPeachey]

What happened?

I was attempting to test Dexie's websocket protocol using testnet and tried to self-accept an NFT offer to test the emitting mechanism, however, I get an error in the GUI stating Trade for this offer already exists.. I have also encountered the same error using the Wallet RPC take_offer.

I've asked about this in the support channel on Keybase, and a kind Kiwi asked the engineering team, and said:

the offer accept code was modified to add checks to ensure you don't accept the same offer twice. I appears the code is looking at all transactions so it's seeing both the offer and the accept and seeing it as a duplicate transaction, hence the message

However, I would like the ability back to self-accept offers for testing purposes, even if it's just on testnet as I think this was an unintentional consequence of the aforementioned changes.

Are you offering an NFT? And what are you asking for in return for the offer?
