Missing `account_id` for "team" actor in webhook payload?

[olan.byrne]

I have an add-on that is performing actions on a repo via the API, triggering webhooks. The add-on operates at the 'account' context, so the actions are carried out by this 'team' account.

There are some inconsistencies in the `actor` webhook payload between a 'team' actor request and a 'user' actor, presumably due to the recent GDPR changes.

`team` account (no `account_id`)

"actor": {
     "username": "myteam",
     "display_name": "MyTeam",
     "type": "team",
     "uuid": "{062ef8e7-1438-4007-ac7e-4dae77d4f999}",
     "links": {
         "self": {
             "href": "https://api.bitbucket.org/2.0/teams/%7B062ef8e7-1438-4007-ac7e-4dae77d4f999%7D"
         },
         "html": {
             "href": "https://bitbucket.org/%7B062ef8e7-1438-4007-ac7e-4dae77d4f999%7D/"
         },
         "avatar": {
             "href": "https://bitbucket.org/account/myteam/avatar/"
         }
     }
 }

`user` account (with `account_id` present)

"actor": {
    "display_name": "Jane Bloggs",
    "uuid": "{9230127a-58bf-4100-9626-6c389e3ee999}",
    "links": {
        "self": {
            "href": "https://api.bitbucket.org/2.0/users/%7B9230127a-58bf-4100-9626-6c389e3ee999%7D"
        },
        "html": {
            "href": "https://bitbucket.org/%7B9230127a-58bf-4100-9626-6c389e3ee999%7D/"
        },
        "avatar": {
            "href": "https://avatar-management--avatars.us-west-2.prod.public.atl-paas.net/initials/jane.png"
        }
    },
    "nickname": "jane.bloggs",
    "type": "user",
    "account_id": "5cd96a53d210950fd02d2999"
},

This is causing issues in some integrations, such as AWS CodeBuild, which expects an `account_id` to be present in the webhook payload.

{
  "message": "Invalid Webhook request received: Missing 'actor account id' field"
}

My question is, given the recent GDPR changes, is it expected that there is no `account_id` for a team, or is this something that is due to be added?
