FilteredClassPathRunner should set the TCCL while creating the test class

[wilkinsona]

FilteredClassPathRunner doesn't set the TCCL when creating the test class. This means that the test class's fields are initialized while the TCCL is the app's class loader. This causes a problem with a field that's declared like this:

private AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();

The application context is left with its ClassLoader being the app class loader. It needs to be the filtered class loader otherwise class cast exceptions are likely to occur during test execution.
