[Bug]: direct_replier.py sample is broken

[TrentDaniel]

Bug Description

• Line 27 has a an improper comparison to None with request.get_payload_as_string() != None
• Line 41 references a variable outbound_msg_builder when no variable under that name has been instantiated

Expected Behavior

• Line 27, the comparison should be written as request.get_payload_as_string() is not None
• Line 41, instead of referencing outbound_msg_builder, self.message_builder should be referenced

Steps to Reproduce

Reproduction not required, just look at source.
