fix for using .lnk files when running app from UNC

Since "" is an invalid target for a .lnk file,
we can return false for doStat() in case of resolving
the .lnk to "".

Notice that .lnk files only allow absolute paths for the target.

"" is returned by readLink in case the .lnk file does not exist.
