Fix logging before parsing logging cmd line args (#1723)

When using --log-file stdout to redirect turnserver logs to stdout
instead of creating a log file, a default log file was still being
created. This happened because the --log-file argument was processed
after logging had already occurred during startup.

Fix #1670
