The /ansible get-jobs command fails if output includes a job that was started by schedule

[ubajze]

Environment

• Python version: 3.6.1
• Nautobot version: 1.0.3
• nautobot-plugin-chatops-ansible version: 1.0.1

Steps to Reproduce

1. Run the /ansible get-jobs command in Slack. Make sure that you include a job that is started by a schedule.

Expected Behavior

I expected to see the list of jobs.

Observed Behavior

The following is displayed in the output:

*An internal error occurred:
'created_by'* :warning:

The job dict does not have the "created_by" dict because a schedule started it.
