Send permanent dameon failures to the log, even when not running in verbose mode

Summary:
Fixes T12803. An install is having difficulty diagnosing mail failures, and one component is that permanent task failures aren't reaching the log.

It's reasonable to send these to the log even when "phd.verbose" is off. See T12803 for a rough review of when we generate these failrues today.

Test Plan:

• Faked some exceptions.
• Got a result in the log (P2058) with phd.verbose turned off.
