Remote events don't work for SingleCall services

[yallie]

Describe the bug
If a service is registered with SingleCall or Scoped lifetime, remote events don't work.

To Reproduce
Steps to reproduce the behavior:

1. ServerFixture: use container.RegisterService<ITestService, TestService>(ServiceLifetime.SingleCall);
2. Run Events_should_work_remotely unit test
3. Event handler is not called

Expected behavior
Client-side event handler should be called.

Additional notes
Looks like factory registration doesn't break the client events:

container.RegisterService<ITestService>(() => new TestService(), ServiceLifetime.SingleCall).
