Compile errors in AsynchronousHTTPServiceTestCase

[robertpenner]

Three compile errors occur in AsynchronousHTTPServiceTestCase: completeHandler, ioErrorHandler and securityErrorHandler are not found.

Changing the superclass to AsynchronousTestCase resolves the issue (currently TestCase).

I am having troubles with Git thinking all my files are changed when they're not, otherwise I would do the fix myself.

I managed to submit the fix in my fork and sent a pull request.
