Fix inlined test cases so they print out the correct command to run when they fail instead of printing out incorrect information.

To fix this I added a new method to TestBase:

    def getRerunArgs(self):
        return " -f %s.%s" % (self.__class__.__name__, self._testMethodName)
        
The InlineTest which inherits from TestBase then overrides this function with a custom version which does the right thing.
