iOS wallet won't import cert that web-validator and android wallet say is valid

[stuartf]

I've issued v2 certs on ethereum-ropsten that import fine into the Android wallet and verify on the universal verifier at https://www.blockcerts.org but they won't import into the iOS wallet the only error it gives is invalid credential

One of the certs can be found at http://certs.blockcerts.gatech.edu/27e2a536-dc91-4066-a50b-be42ee4d29f9.json

I tried issuing on bitcoin testnet (cert here: http://certs.blockcerts.gatech.edu/dcf9a65a-15d4-42a8-b390-13bd5a187e18.json) and we get the same issue. Imports to android wallet and verifies on web validator, but iOS wallets say it's invalid.

We figured out that this was because badge.issuer.revocationList is set to null in our certificates.
