xRemoteFile always returns false in test

[shurick81]

As a devops, I expect to be able to test if the system is in desired state, including xRemoteFile resources. Here is an example of the resource I am applying:

        xRemoteFile SQLMediaArchive
        {
            Uri             = "http://$env:PACKER_HTTP_ADDR/SQLServer2014SP1.zip"
            DestinationPath = "C:\Install\SQLServer2014SP1.zip"
        }

First, I run Start-DscConfiguration and the file is downloaded successfully. Then I need to test that configuration is in desired state, so I run Test-DscConfiguration and I get False:

Setting MatchSource = $false helped. I think it would be nice to mention in documentation that by default it's $true.
