Commented Issue: Error on authentication error under non-interactive mode [3580]

I noticed a minor exception from the NuGet.exe on the case it failed to authenticate with a feed under non-interactive mode.
Previous builds of NuGet reported the error in more user-friendly fashion:

Checking packages on source: Feed: http://localhost:1025/nuget/User: aaa, Password
Please provide credentials for: http://localhost:1025/nuget/
UserName: Failed to check package sources information for URI Feed: http://localhost:1025/nuget/User: aaa, Password. Cannot prompt for input in non-interactive mode.
System.InvalidOperationException: Cannot prompt for input in non-interactive mode.

Comments: Moving this out of the 2.7 release; we're not going to be able to fix this in our 2.7.1 update of nuget.exe.
