integrations/trello: Stop logging to CSV file in Trello script.

The information logged to the CSV file is largely redundant, since
the ID of the webhook is already printed to the screen once a
webhook is setup correctly.

Since this is a script that the user is required to run
once, we should minimize its reliance on external files as much
as possible. This makes it easier to run the script when one
is SSH-ing into a server and doesn't really care about where
the script lives, for instance.
