Eduardo Antuña Díez a2082bae5c Avoid overwriting a domain that can be resolved by DNS
According to the current implementation any domain ending in .eth or .test will try to resolve through ENS even if the DNS is able to resolve it.
changing `onBeforeRequest` to `onErrorOccurred` will only resolve those .eth or .test domains that the DNS is not able to resolve.
