Fix log message so that it's valid JSON

[mtwomey]

Existing log message looks like this:

message: '{"topicId":"20343","postId":69782,"postContent":"<p><a href=\\"/users/Will1911\\" 
title=\\"@Will1911\\">@Will Adams</a> Another clarification – we wanted to begin with just the 
responsive web application, correct? This will give you the correct sizing to display on a mobile 
phone AND it will allow your customers to access it on their computer. Instead of begining with the 
mobile app, I believe you decided on the web app, but please correct me if I am mistaken! Thanks!
</p>","userId":23090277,"projectId":"4766","initiatorUserId":23090277}' } }

Either the whole thing needs to be valid JSON, or the string after 'message:' needs to be valid JSON (note the extraneous curly brackets at the end as well as the fact that things are double-escaped).

The log should lint properly at: https://jsonlint.com/

This is needed for easy parsing of the message in Sumologic.

@gondzo Can you add this the next chunk of work please? Not super urgent, but would be very helpful for Sumologic.
