Remove nil content from Duo Chat message history
What does this MR do and why?
An error was occurring on Duo Chat where for some reason, the content in a message's history was saved as nil.
We are not sure why this happens. It could just be a blip. It does not seem particularly common as not many users are affected.
In any case, once nil content is saved to the user history, Duo Chat will never work for their user again until they type /clear

How to set up and validate locally
It is tough to cause this scenario manually, so I just recommend a quick regression test of Duo Chat.
