    Fix broken schema validation

    - Add call to validate value in resolve_value. This way all the
      children in a map will be validated.
    - Remove explicit check of string type in String validation since
      everything could be considered a string. This is needed because the
      version is now being validated and we allow version to be a float or
      string.
