The error event is not cleaned up on successful read

[szmarczak]

const getStream = require('get-stream');
const {Readable} = require('stream');

const stream = new Readable({
    read() {
        this.push('chunk');
        this.push(null);
    }
});

const buffer = await getStream.buffer(stream);

console.log(stream.listenerCount('error')); // => 1
