Consolidated project references within OnTopic.AspNetCore.Mvc.Tests

The `OnTopic.AspNetCore.Mvc.Tests` project relies upon the ``OnTopic.AspNetCore.Mvc.Host` project, which in turn relies upon the `OnTopic.All` project. As such, there's no need or benefit to explicitly referencing each of the individual projects.
