Could we just change the default exception_message to 'Exception suppressed.' ?

Im not the biggest fan of this. If people are being specifically confused by the
logdog exception spam, you could just set the exception_message arg as like
'Ignore this exception, crbug/123456' in logdog_helper or w/e it is being
raised.

Done.
