Enum of type boolean and array omitted

Problem:
When defining a model with a boolean enum with only one value, true for example, the swagger-parser does not load in the enum value.

Use Case:
This is needed when setting a required parameter that only accepts true for example.

Get the spec parsing results with:

java -DdebugSwagger -jar /usr/local/Cellar/swagger-codegen/HEAD-e15bbc9/libexec/swagger-codegen-cli.jar generate -l python -i client.yaml -o client/ -DpackageName=client

Parsed spec, definitions result:

        }
      }
    }
  }
}

We see that none of the booleans bool_item_1 to bool_item_9 loaded in true as an enum value.
Please fix the parser so it correctly sets the boolean enum value.
