Local development reload issues

[levithomason]

@layershifter I've noticed after the latest round of build changes that editing an example source file in watch mode does not work correctly. The exampleSources.json gets rewritten with only a single example entry, so all the other examples are missing. Perhaps you could take a look?

Steps

1. yarn start

2. Navigate to /elements/button

3. See all examples are rendered and exampleSources.json includes all examples

4. Edit ButtonExampleButton.js

5. 🐞 There is no HMR or page reload

6. 🐞 exampleSources.json now looks like this:

   {
     "elements/Button/Types/ButtonExampleButton": "import React from 'react'\nimport { Button } from 'semantic-ui-react'\n\nconst ButtonExampleButton = () => <Button>Click Here!</Button>\n\nexport default ButtonExampleButton\n"
   }

Initial Load

After editing ButtonExampleButton.js

💥 Will take a look tomorrow, @levithomason your reports are awesome ❤️
