Reporting isVisible for free element

[skovhus]

For elements that do not have a size in the DOM, react-visibility-sensor currently reports that it is visible.

I think this should be the first check:

if (rect.top + rect.right + rect.bottom + rect.left + rect.width === 0) {
  isVisible = false;
}

@skovhus good idea, and thanks for the PR! I'll get to it soon I promise :)

Awesome lib @joshwnj! Any timeframe on getting this into a release? Would be super helpful 👍

[joshwnj]

thanks @neeharv . We're nearly ready to release this, just need to do some final reviews of #51

If you're able to help by pulling that branch and making sure things still work as expected, that will speed up the process a lot :)
