`TypeError` when rendering `Object.create(null)`

[nolanlawson]

<template>
    {obj}
</template>

export default class extends LightningElement {
  obj = Object.create(null)
}

The above errors out with TypeError: Cannot convert object to primitive value.

This is a niche use case, because if you use obj = {} then it renders [object Object] instead. But maybe we should support this?
