Check for error before checking for data end

[AquiGorka]

I was getting an error in the lines of: "cannot read end of undefined" which meant data was undefined. Maybe this was happening because an error was being sent but the check for it happened after trying to access data.end

I changed this locally and the error stopped.

Thanks!

I assume you'll update js-libp2p-websocket-star and we'll have to ask js-ipfs to update accordingly.

[mkg20001]

I think there is no need to update that there as it's currently being rewritten anyways
PR: libp2p/js-libp2p-websocket-star#43 - just waiting for that to get reviewed

[AquiGorka]

Oh, ok. Thanks.
