Restore COM extended error info reporting for failed COM calls

It would be nice to add a test for this, but first I'll have to identify
a suitable friendly COM component with which sets IErrorInfo to provoke
into providing an error. The only COM object implemented in the image which
does this is AXPropertyBag, and it is returning a list of errors through
a special log parameter.
