noWrapper prop isn't used

[nathnhughes]

Not sure if this lib is still being maintained as there hasn't been much activity in a while but i've come across an issue when using the noWrapper prop.

When doing something like:

<LazyHydrate whenIdle noWrapper="nav">
    /* ...complex component ... */
</LazyHydrate>

the tag specified in noWrapper is ignored and just the children are returned.

I've put together an example repo here: https://codesandbox.io/s/strange-napier-6tvbp4?file=/src/App.tsx

From a quick look over the code, my guess is it has something to do with the if statement on line 168:

react-lazy-hydration/src/index.tsx

Lines 168 to 170 in 8faafaa

	if (noWrapper) {
	return children;
	}

It looks like that's checking whether noWrapper exists rather than whether its actual value is true...

if (noWrapper) { // here noWrapper could be string or true
  return children; 
}

but the problem may be deeper than that.
