Remove "body" type parameter check in `shouldIncludeParameter`.

From what I understand, the call was redundant:
- in the original code, it always returned true because it was inside
  a condition of "has no annotations", and `paramTypeOf` will return
  "body" for that condition (also risking NullPointerException if the
  annotations == null)
- in the modified code all the allowed/excluded conditions are tested
  first, leaving only unrecognised annotations in the end, which would
  return "body" from `paramTypeOf` as well.

Therefore, the explicit parameter type checking is unnecessary.
