BUG/MINOR: rules: suppress requestLogging default (again) (#176)

In e293b90 (BUG/MINOR: rules: suppress requestLogging default), an
attempt to suppress the diff creation when requestlogging was not
specified (e.g. default) was made. However, it seems that the patch
confused "new" and "old" values. This commit properly swaps the order
and produces the expected results.
