Prevents WebURLLoaderMock to crash when didReceiveResponse calls ::cancel().

Prevents WebURLLoaderMock to crash when didReceiveResponse calls ::cancel().

The fix is a bit dirty but it should work and is straightforward. The
clean solution would involve more changes on the Blink side or some
wrapping of objects in WebURLLoaderMock.

Is this fixing some bug?

I'd prefer someone working more closely with this code to review, and I'd be
happy to stamp for OWNERS.

Yes, it is preventing the tests from the following CL to crash:
https://codereview.chromium.org/295063002/

I'm using the WebURLLoaderMock with a Resource instead of a RawResource which
means that I am taking another code path that, I guess, wasn't tested with that
mock.
