Remove Internet Explorer dependency from test_QueryService.py.

[junkmd]

Related to #302

This focuses on removing the InternetExplorer.Application dependency from comtypes/test/test_QueryService.py.

The test now manipulates and verifies MSHTML COM objects (HTMLDocument, etc...) instead of relying on an InternetExplorer.Application instance.
