Rest of the tests could not be run as the test runner would break here. This change adds a check to fail when the FileLoggerAdapter returns an empty array from here: https://github.com/ParsePlatform/parse-server/blob/master/src/Adapters/Logger/FileLoggerAdapter.js#L191
Regarding the cause of the error itself, it is due to different filename separators in *nix and Windows. The FileLoggerAdapter would not save logs (have not tested this). This is a separate issue and should also be fixed.
