Add displayName

[binomialstew]

Using react@16.3 and enzyme@3.3.x to test, the name of the component is now <t> when previously in react@16.2 it was <ReactTooltip>. Setting the displayName property on the component class ensures the name will remain as ReactTooltip. For example, using enzyme:

expect(ShallowInstance.children().last().name()).to.equal('ReactTooltip')

Awesome, thanks!

If you would like your fix to trigger a release, reformat the commit message commitizen-style, like this:

fix(index): Add displayName

I'm glad to contribute. Thanks for the tooltip. I hadn't seen commitizen before. Do you want me to close and reopen with the updated commit message?

@aronhelser, I found that this is actually due to changes in webpack 4, and the name is retained when using development mode. For example, in karma.config.js:

module.exports = {
  ...
  webpack: {
    ...
    mode: 'development',
    ...
  }
}

Anyway, I still think it isn't a bad idea to define your displayName, in case you'd still like to merge this PR.
