Logs errors as Debug and not Display

[tomaka]

All the logs that look a bit "system-y" (which are all the debug and trace logs) now show errors through the Debug trait rather than Display

This fits the vibe of the log line more, and also provides additional information.

The Display trait is still used for warning and error logs that the user is expected to react to.
