Migrate all console.log to use probot logging

## Problem Description

Hi all, there are a few places where `console.log` is being used in place of probot logging. Many of these look to be debug/testing logs. I was thinking of going through and moving them all to use probot logger, but there is nothing to prevent further usage in the future. Any thoughts on ensuring correct logging is used? I see the project uses `standard` right now, which doesnt allow for doing so via eslint.

If we reach consensus, I am happy to do the work
