I had a VPN connection which I used frequently. Today it was missing in the NetworkManager connections screen and I realized it was missing altogether from /etc/NetworkManager/system-connections/.

Here is the log but I think I did not delete the connection.

The log seems to show that you (the user with user-id 1000) did first fail to delete the connection and then succeeded with the next try. 
Personally, I have disabled “audit” (too many messages that are useless to me).
Is there no context to be had from your logs?
… eg: the full log sequence around that time, not just these two specific lines
As I suspect I did it myself mistakenly. I didn’t follow up and it didn’t happen since.
