Note: this reproduces on macOS only

Steps to Reproduce (link):

1. ln -s source target on a folder to link it to another folder
2. add this linked folder as single entry to a workspace file
3. open that workspace file
4. change files outside and see the explorer not updating

Steps to Reproduce (wrong casing):

1. add a folder to a workspace config file that uses wrong case (e.g. desktop instead of Desktop)
2. open that workspace file
3. change files outside and see the explorer not updating

=> it looks like the NSFW watcher service should probably do a similar trick as our chokidar watcher and realcase the folder path (and possible realpath to resolve the link first).

The important thing is to restore the original path from the file events to not confuse the consumers.
