This commit fixes log archiving/rolling when using Profiles.  Profiles mode programatically messes with NLog config... Unfortunately it suffered from a copy/paste error and was overwriting the ArchiveFileName for a target with the FileName for that target.  The effect of the defect is that once a log file gets to a million bytes in size, each log statement there after will throw an exception.

Sorry for mixing this in with 'intervals' but I didn't have an easy way to put it anywhere else.
