Out of bounds, please use a smaller from_index

[ryancwalsh]

Basically, to update what we were thinking in https://github.com/NEAR-Edu/near-certification-tools/issues/52 now that we know about the burning event, we're now thinking:

• When we invalidate a cert, since we want it to no longer appear in someone's wallet, we should emit a burn event.
• We also want (hopefully just for now, pre-launch) the ability to completely delete certs, which should also emit burn events and remove them from wallets.
• We seem not to need the concept of a trash account

So then you did some commits like https://github.com/NEAR-Edu/near-certification-tools/commit/c8e40e1c90d9f81ab2052d28b6362a518b123d0b

And now it's possible to delete certs. 🎉

But here is a new issue:

@ryancwalsh Rebuild, redeploy (no migration necessary). The accounts from which all certificates were deleted will be in an invalid state. To recover them to a valid, empty state, mint them new certificates and delete them again, and it will reset to the correct empty state.

@encody I don't know if I'm doing something wrong, but I pulled the latest main, rebuilt, redeployed, minted a new cert for ryancwalsh.near, and then tried to delete it:

@ryancwalsh a certificate with that ID doesn't exist

[ryancwalsh]

@encody You are right; my mistake! I think in my attempt above I must have issued the new cert on testnet. Trying again just now on mainnet and then deleting, everything worked! Thanks!
