Fix JSON messages in history

[MDrakos]

DX-2195 Running `state history` in dashboard-created Windows project shows JSON in "changes" section

This change isn't ideal but it will work for now until we can get the history in the format of a build expression. Asked the Dashboard squad how they are handling this. Here is their changeset: https://github.com/ActiveState/TheHomeRepot/pull/11922/files.

Here is an example of the updated output:

This looks fine to me, but we should add some more tracking info.
