Deleted credential cannot be readded to wallet

[bmuramatsu]

From reset wallet. Finish setup.

Add credential from digitalcredentials/docs#10 multiple credentials with invalid signature:

Delete second credential. Only 1 credential remains in the wallet.

Try to readd credentials using the same two from QR code.

Both credentials appear as "Aready in Wallet"

But, only 1 credential in the wallet...

@bmuramatsu Thanks for the repro documentation. I've added a story in PT and will take a look at it.

Appears to be resolved, I forget which PR, closing this.

I believe this is still an issue.
We're using the id field to differentiate credentials but not all contain an id so it treats them as duplicates.
We discussed using the proofValue to identify credentials going forward.
