docs: Return the Payload attached to the current active bucket for |test|.
  Always returns a payload so the client doesn't crash on a malformed
  test definition.
  
  @param testName test name
  @return pay load attached to the current active bucket
  @deprecated Use {@link #getPayload(String, Bucket)} instead
