Fix error on complex example

[tteke]

What: Fixing an error on readme

Why: In the complex example catch already sets error to error.message. So in render, it should just show state.error.

How: Render function updated to just show state.error instead of state.error.message.

Checklist:

• Documentation added to the
  docs site
• Tests N/A
• Typescript definitions updated N/A
• Ready to be merged
  
  Yes. Either that or catch shoud update error on the state as error: error instead of error: error.message

Hi, I have a question about the above syntax.

Is it some convenience to handle show/hidden a component like in README.md?
{ isTrue ? <Component /> : null }

than (shorter a way)
{ isTrue && <Component /> }

I could write a blog post about this for the number of times I talk about it 😅

Basically I've been bitten by this before:

{contacts.length && <RenderContactList contacts={contacts} />}

If contacts.length is 0 then you'll render 0. No good. Shipped that to prod at PayPal. So I never do that and instead I always go with the more explicit version:

{contacts.length ? <RenderContactList contacts={contacts} /> : null}

But you do whatever you like :)
