Add check for unbound user object before kafka producer step.

[tjacovich]

When a user logs in, the current_user object becomes unbound from it's session, resulting in an error when the producer attempts to access the object for the purpose of generating the kafka message. This PR adds a check to make sure the user object is still bound.
