Fix 4 unit test failures 

- NRE in TypeExtensions.IsCompatibleWith()
- ComplexModelDtoResultTest.Constructor_ThrowsIfValidationNodeIsNull() won't work w/o validation
- BindModel_Error_FormatExceptionsTurnedIntoStringsInModelState() looking for wrong message
- BindModel_Error_FormatExceptionsTurnedIntoStringsInModelState_ErrorNotAddedIfCallbackReturnsNull() a dupe
- Also add [NotNull] attributes in TypeExtensions
