NS5000 when checking if an event subscription was received. about nsubstitute.analyzers HOT 4 CLOSED

@dtchepak I am trying to add valid test case for this scenario and I came up with this

using NSubstitute;
using System;
using Xunit;

namespace MyNamespace
{
    public class Foo
    {
        public event Action SomeEvent;
    }

    public class FooTests
    {
        [Fact]
        public void Test()
        {
            var substitute = NSubstitute.Substitute.For<Foo>();
            substitute.Received().SomeEvent += Arg.Any<Action>();
        }
    }
}

However, this test passes, even though SomeEvent was not fired - according to docs
it is one of the way of asserting if event subscription was received. Is this valid test case in this case or there is regression in NSubstitute?

This is because the member is not virtual. Running multiple tests including this one gives me:

  Error Message:
   NSubstitute.Exceptions.RedundantArgumentMatcherException : Some argument specifications (e.g. Arg.Is, Arg.Any) were left over after the last call.

If it is virtual it fails as expected.

  Error Message:
   NSubstitute.Exceptions.ReceivedCallsException : Expected to receive a call matching:
        SomeEvent += any Action
Actually received no matching calls.

Ahh right. I dont know why I thought that events were handled differently. Will update my PR accordingly

Can you release an update with this fix to NuGet, please?
