[🐞] v2: render function behavior

[wmertens]

Which component is affected?

Qwik Runtime

Describe the bug

In v2, tasks that return Promises throw those Promises, forcing re-running after completion, but in v1 they just chain on a single Promise that is awaited.

Reproduction

Steps to reproduce

import { component$, useTask$, useSignal } from '@builder.io/qwik';

export default component$(() => {
  console.log('before')
  useTask$(async ({ track }) => {
    console.log('task A');
    await 5
    console.log('task A async');
  });
  console.log('between');
  useTask$(async ({ track }) => {
    console.log('task B');
    await 5
    console.log('task B async');
  });
  console.log('after')
  return (
    <div>hi</div>
  );
});

in v1 this gives

 before
 task A
 between
 after
 task A async
 task B
 task B async

and in v2

 before
 task A
 task A async
 before
 between
 task B
 task B async
 before
 between
 after

the v1 behavior is correct
