add further step to avoid message summary from breaking

[Wladastic]

Background

It is already known that message summary could break or overwrite the message history,
I encountered a few problems which these two changes fix.

• making sure that the new_messages are a deep copy as it turned out to break on my runs (less often, but happened)
• adding extra escaping to make sure json conversion will not break.
