BUG: lpass show -j does not show "additional fields"

[jwilliams-shadowsoft]

In the example below I add a secret "nothing/boring" with:

• Password - a standard field
• Port - a non-standard or additional field

Results:

• lpass show nothing/boring shows all data in the secret
• lpass show nothing/boring -j omits the additional field

Test session:

$ lpass add nothing/boring --non-interactive
Username: Nothing
Port: 8080

$ lpass show nothing/boring
nothing/boring [id: 3692150305173701752]
Username: Nothing
Port: 8080

$ lpass show nothing/boring -j
[
  {
    "id": "3692150305173701752",
    "name": "boring",
    "fullname": "nothing/boring",
    "username": "Nothing",
    "password": "",

    "group": "nothing",

  }
