Parsing error when we have object inside object

[Zorin95670]

Describe the bug

When we try to parse a tf like:

data "aws_ami" "web" {
  filter {
    name = "state"
    test {
      value = 8
      test2 {
        value  = 9
      }
    }
  }
}

We have an unexpected parsing error.

So, the parser can't manage object inside object. We have to fix it !
