Un-used edge agent is pinging and filling logs on fresh instance

[ghost]

Is your feature request related to a problem? Please describe.
I previously had an edge agent set up, then configured a fresh instance of Portainer but the logs are being filled with error http error: Unable to find an endpoint with the specified identifier inside the database (err=Object not found inside the database) (code=404) from the edge agent trying to check in.

Describe the solution you'd like
Don't fill the logs with this message, or make it clear that there is an old edge agent trying to check in
