PR Summary

On WSL, if you have a folder in /mnt/c/Users/steve/Blah and try: test-path /mnt/c/Users/steve/blah -pathtype container you get an error because .First() is being called on an empty string array. Fix is to check that the returned array contains something. Otherwise, just return the given path as some file system issue prevents correcting the casing. This issue seems to only repro on WSL (Windows Subsystem on Linux)
