Profile Management requests sends Request ID in POST Body instead of Query Parameter

[aeneasr]

Describe the bug

Instead of setting the Request ID in the action part of the JSON Payload, it is set as a hidden field:

{
  "id": "48068b5d-3438-4d6f-9955-331b96c41762",
  "expires_at": "2020-01-27T23:03:58.5986947Z",
  "issued_at": "2020-01-27T22:03:58.5987099Z",
  "request_url": "http://127.0.0.1:4455/profiles",
  "form": {
    "action": "http://127.0.0.1:4455/.ory/kratos/public/profiles",
    "method": "POST",
    "fields": {
      "csrf_token": {
        "name": "csrf_token",
        "type": "hidden",
        "required": true,
        "value": "+5+WxP7+leOpfjHHkWWe99APD7845i82p4wGtfdWKHBK5fFg4BS7JjzdeI7kdsOUElyrG10ZR5vIqi7asNpqAA=="
      },
      "request": {
        "name": "request",
        "type": "hidden",
        "required": true,
        "value": "48068b5d-3438-4d6f-9955-331b96c41762"
      },
      "traits.email": {
        "name": "traits.email",
        "type": "text",
        "value": "aeneas@ory.sh"
      },
      "traits.name.first": {
        "name": "traits.name.first",
        "type": "text",
        "value": "sdfaasdfafsd"
      },
      "traits.name.last": {
        "name": "traits.name.last",
        "type": "text",
        "value": "sdfaasfd"
      }
    }
  },
  "identity": {
    "id": "c631e58a-445a-4844-ae80-f0b426a1e11e",
    "traits_schema_id": "default",
    "traits_schema_url": "",
    "traits": {
      "email": "aeneas@ory.sh",
      "name": {
        "last": "sdfaasfd",
        "first": "sdfaasdfafsd"
      }
    }
  }
}

This should be adjusted to match logic from login/registration.
