Use better state assertions in spec tests

[dapplion]

Motivation

Current spec test assertions show

expected false to be true

This is very hard to work with

Description

Use json data deep equality for much nicer diffs, for example:

1) epoch registry updates mainnet
       ejection_past_churn_limit:

      AssertionError: expected { Object (genesisTime, genesisValidatorsRoot, ...) } to deeply equal { Object (genesisTime, genesisValidatorsRoot, ...) }
      + expected - actual

           {
             "activationEligibilityEpoch": "0"
             "activationEpoch": "0"
             "effectiveBalance": "16000000000"
      -      "exitEpoch": "6"
      +      "exitEpoch": "5"
             "pubkey": "0xac9b60d5afcbd5663a8a44b7c5a02f19e9a77ab0a35bd65809bb5c67ec582c897feb04decc694b13e08587f3ff9b5b60"
             "slashed": false
      -      "withdrawableEpoch": "262"
      +      "withdrawableEpoch": "261"
             "withdrawalCredentials": "0x00842cef589da28d85b18f7655b70bd2e6d49dd682fb50f75c44293e9de9897a"
           }
