fix(#212): avoid empty download folder in loaded settings

Added a URL test in settings middleware to avoid empty or invalid download folder on loading the settings file.

Also
- Added some additionnal logging to report errors in the log on downloading results
- Handle a possible case of download results called on a job without results
- Avoid to delete the engine job if it has not been downloaded
