[issue12376] unittest.TextTestResult.__init__ breaks under complex __mro__

[Ben Ranker]

New submission from Ben Ranker :

TextTestResult.__init__(...) calls super(TextTestResult, self).__init__() with 
no args. If a custom TextTestResult descendant has a complex inheritance 
hierarchy that puts another class between TextTestResult and TestResult in the 
__mro__, then that class doesn't receive the common stream, descriptions, and 
verbosity args. If it needs them to function then the __init__ chain explodes.

See attached breakunit.py for an example of this.

Sorry for any confusion caused by my imprecise use of the word "explodes."
