[Bug]: Wrong value while chaging between body types for Environmental variables

[corderop]

What happened?

In a request, when you have inserted some value set with an Environmental variable in the body and you change it to JSON type, instead of using the content of the env variable, it uses some UUID. I suspect it's the identifier of this env var.

Steps to reproduce?

1. Create a POST Request
2. In the body tab, select Form URL-Encoded type
3. Add a value with an env variable
4. Change to JSON type
5. The body will not have the correct value in the Env variable field

{
  "grant_type": "authorization_code",
  "code": "#random_uuid#",
  "redirect_uri": "http://localhost/"
}
