[🐞] Return value of the tagged function is only reactive if it is alone in an element.

Which component is affected?

Qwik Runtime

Describe the bug

I am making an i18n tool using tagged function to embed translative message in a jsx. I found it doesn't reactively update when the locale has been changed in a condition that the title says.

Here's a simple example that causes this issue.

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

const useFoo = (counter:Signal<number>) => {
  const state = useStore({});
  return (s:TemplateStringsArray) => {
    const key = s[0];
    useTask$(({track}) => {
      const count = track(() => counter.value)
      state[key] = `${key} - ${count}`
    })
    return state[key];
  }
}

const useBar = (counter:Signal<number>) => {
  const state = useStore({});
  return (key:string) => {
    useTask$(({track}) => {
      const count = track(() => counter.value)
      state[key] = `${key} - ${count}`
    })
    return state[key];
  }
}

export default component$(() => {
  const counter = useSignal(0);
  const t = useFoo(counter);
  const s = useBar(counter);
  return <>
    Count up
    <div>{t`hello`}</div>
    <div>{t`world`}!</div>
    <button onClick$={() => counter.value++}>Click</button>
    <div>{s("hello")}</div>
    <div>{s("world")}!</div>
  </>;
});

There are 4 lines that show message with counter value. I have expected all of them are reactively updated when I click the button. But the 2nd line does with no luck. This is strange.
