getAll handler is currently broken and needs fixing.

[addievo]

Describe the bug

The NodesGetAll handler needs to be fixed. I did a monkey patch while testing and it needs to be applied to Polykey.

// client/handlers/NodesgetAll.ts

for await (const [index, bucket] of nodeGraph.getBuckets()) {
            for (const [id, info] of bucket) {
                const encodedId = nodesUtils.encodeNodeId(id);
                // For every node in every bucket, add it to our message
                if (ctx.signal.aborted)
                    throw ctx.signal.reason;
                yield {
                    bucketIndex: index,
                    nodeIdEncoded: encodedId,
                    host: info.address.host,
                    port: info.address.port,
                };
            }
        }

To Reproduce

1. Run nodes getall in Polykey-CLI.

Expected behavior

Shouldn't throw an error and succeed.
