Subject: Don't print root_cause if there's only one error in the chain

If there's only one error in the chain, it prints:

    error: no matches for event ID: no matches for event ID

Now, it will print:

    error: no matches for event ID

and:

    error: unable to open OAuth secret file: Not a directory (os error 20)
