fix: address the review of the issue fixes

Nine cmdlets still read the PWD variable for the default location when
-Path was omitted, so #86 remained for that form; they now use
GetCurrentLocation. Copy-Item2 writes the object that CopyTo returns for the
copy instead of relying on AlphaFS to update the source object, and a test
covers a folder.
