Various rehash fixes that it seems were introduced by untested code.

- Remove unused ReportConfigError member
- Don't report successful load (and spam modules that failed to load) if there is a config error
- Restore server name before attempting to send error string to client(s) otherwise most of them won't recieve the notifications.
Fixes bug #891. Still to come: report errors loudly on startup regardless of debug mode.
