Rest call returns wrong datatype in MDL source

[rbolt]

Problem

Call Rest services gives wrong output datatypes if configured to return the following:

• System.FileDocument, or an object that has System.FileDocument as generalization
• System.HttpResponse or an object that has System.HttpResponse as generalization

MDL Output for FileDocument

Got:

$fileResponseGet = rest call get '{1}' with ({1} = $location)
    header '1' = $header
    auth basic $username password $password
    timeout 300
    returns String;  <-- WRONG OUPUT

Expected

$fileResponseGet = rest call get '{1}' with ({1} = $location)
    header '1' = $header
    auth basic $username password $password
    timeout 300
    returns System.FileDocument (or the fully qualified name of the specialization); <-- EXPECTED OUPUT

MDL Output for HttpResponse

Got

$httpResponseGet = rest call get '{1}' with ({1} = $location)
    header '1' = $header
    auth basic $username password $password
    timeout 300
    returns response; <-- WRONG OUPUT

Expected

$httpResponseGet = rest call get '{1}' with ({1} = $location)
    header '1' = $header
    auth basic $username password $password
    timeout 300
    returns System.HttpResponse (or the fully qualified name of the specialization); <-- EXPECTED OUPUT
