posting poorly structured sample data to a /v2/meters/meter causes 500 instead of 400

[Chris Dent]

When making a request like the following with poorly structured sample data the response is 500. It should be 400.

    - name: post bad samples to meter
      desc: bad data for samples
      xfail: true
      url: /v2/meters/apples
      method: POST
      request_headers:
          content-type: application/json
      data:
          samples:
              - red
              - blue
              - yellow
      status: 400

    Fixes exception path with the datatype is a Object

    If the object type is ArrayType or DictType, the datatype
    is an object not a class. Currently a 500 error is raise
    just because the exception path for invalid input handle only
    when the datatype is an UserType or Class, not object.

    This change fixes that.
