Native Windows functional tests should log their failure reason, and re-enable Native_ProjFS_MoveFile_PartialToOutside

[wilbaker]

The changes for #382 disabled Native_ProjFS_MoveFile_PartialToOutside.

Native_ProjFS_MoveFile_PartialToOutside should be re-enabled, and the native functional tests on Windows should be updated to log the specific reason that they failed.
