If you create a DirectoryInfo object pointing to a file a call to the
GetFileSystemInfos method will not return an IOException as it does under .NET.

it will instead return an array of two FileSystemInfo objects containing the
same details.

Reproducible: Always

Steps to Reproduce:
Using the csharp console program enter the following commands:

using System.IO;
var di = DirectoryInfo("/path/to/file");
di.GetFileSystemInfos();
Actual Results:  
The console will print:
{ /path/to/file, /path/to/file }

Expected Results:  
An IOException should be thrown.
