NuGet_PSModule has Key on Ensure instead of Name

[gaelcolas]

Using NuGet_PSmodule with 2 packages fails with the following error:

$$$$$$ Test-ConflictingResources : A conflict was detected between resources
$$$$$$ '[Nuget_Module]PSRabbitMQ (::128::9::Nuget_Module)' and
$$$$$$ '[Nuget_Module]RabbitMQTools (::135::9::Nuget_Module)' in node 'localhost'.
$$$$$$ Resources have identical key properties but there are differences in the
$$$$$$ following non-key properties: 'Version;Name'. Values '0.1;PSRabbitMQ' don't
$$$$$$ match values '1.0;RabbitMQTools'. Please update these property values so that
$$$$$$ they are identical in both cases.

I believe it's a mistake in the resource key that is on 'ensure' instead of name.
It should be like:

[DscResource()]
class Nuget_Module {
  #Declare Properties
  [DscProperty(Mandatory)]
  [ensures] $Ensure
  [DscProperty(Key)]
  [string] $Name
  [DscProperty()]
  [string] $Version
  [DscProperty(Mandatory)]
  [string] $ProviderName
