Add xUnit analyzers and take fixer suggestions (4 of 5): System.Web.Http.Tracing.Test to System.Web.Mvc.Test
- part of #65 Few manual changes: - use `Assert.IsAssignableFrom<T>(...)`, `Assert.IsType<T>(...)` and `Assert.Single(...)` return values - fix xUnit1026, "`[Theory]` method doesn't use all parameters" issues - turn `[Theory]` that used no parameters into a `[Fact]` - add new dataset properties; see `EncodedDataSets` in particular - `Assert.Equal<T>(...)` -> `Assert.Equal(...)` - avoid Linq's `.Where` inside `Assert.Contains(...)` and similar
