Need to consider should put whether the consensus addr or the validator id in the Slashed event, or both, due to non-validator will be treated as address(0) in slashing double signing.

  1) Slash indicator test
       Single flow test
         Double signing slash
           Should be able to slash non-validator with double signing:

      AssertionError: expected '0x00000000000000000000000000000000000…' to equal '0x4628B9a23BDe2402379A667388e3aF213A7…'
      + expected - actual

      -0x0000000000000000000000000000000000000000
