[issue16288] TextTestResult uses TestCase.__str__() which isn't customisable (vs id() or shortDescription())

Note that str(test) and test.id() don't return the same value.  The former is the "friendly" name.  It is probably intentional that TextTestResult uses the TestCase instance's friendly name in its getDescription() method as opposed to the id.

> TextTestRunner calls str(TestCase) directly, which makes it hard for testscenarios to rename the test cases as it parameterises them

What about testscenarios subclassing the TestCase instances as it parametrizes them?

    class ScenariosTestCase(case.__class__):
        def __str__(self):
            return "testscenarios test name..."
    case.__class__ = ScenariosTestCase
    print(str(case))

>From the documentation, it looks like testscenarios creates new test objects from the originals anyways.  Alternatively (although I don't if testscenarios can control what test runner is being used), TextTestRunner could be subclassed with its own getDescription() method.
