This fixes a crash in IE8 with ChromeFrame when a new tab was created.
ChromeFrame VTable patches the IInternetProtocol interface for the CLSID_HttpProtocol
and CLSID_HttpSProtocol handlers. However we were using the same VTable information to patch both
the handlers essentially overwriting the first one. While this all worked purely by chance, it
exposed a bug in IE8 where every new tab initially goes into a new process and if the chromeframe
is unloaded we would leave behind an IInternetProtocol interface in urlmon patched, which would
crash when dereferenced.
Added a check in the VTable patching code for this case.
