master_key in json file is redundant confusing

master_key value is redundant and confusing it's the same as the owner key and in fact doesn't exist on it's own (it's not well known "Master Password" that were popular in early days)
it's confusing because newbie may thing that after changing all other keys somehow master_key can still be used to manage the account, but that's not true
so I would rather be for just removing it from here

{
  "account_name": "guest4test42",
  "master_key": "5KXjWWYYPY3T5w3zZ2Kg37vGvTEEvXjsRPoidLkAvZaS3c9ahiR",

    },

    "memo": {
      "public_key": "STM7Nya5HtTDYsGUuqS5jyUy7cc5gjA72kMDQjGxACaDyoDiC3bca",

    }
  },
  "_note": "KEEP THIS FILE SAFE! This master key is the key to your entire account. Store it in a secure location and never share it with anyone.",
  "generator": "Hive Bridge v1.0.2 #237591e399503c8eb7f010978fc606552e283d64"
}

Of course those private keys are generated for the purpose of this issue so, no worries, I'm not leaking here anything
