Code coverage proxy waits a long time on resolving the unknown domain name

[canonic-epicure]

This kind of test (waiting for an error on resource loading)

t.it('Should support using external URL starting with // as resourceImagePath', async t => {
        let fired;
        const onError = event => {
            t.is(event.target.src, location.protocol + '//foo.bar/bob.jpg');
            fired = true;
        };

        document.body.addEventListener('error', onError, true);

        scheduler = await t.getSchedulerAsync({
            resourceImagePath : '//foo.bar/',
            resources         : [{name : 'Bob'}],
            columns : [{type : 'resourceInfo']}, 1);

        await t.waitFor(() => fired);
        document.body.removeEventListener('error', onError, true);
    });

fails when using code coverage, because (theoretically) the code coverage proxy tries to resolve the foo.bar domain and probably hangs on that, or waits a long time.

We probably won't be using code coverage proxy, at least for now
