Use CamelCase component name in the Web Component setup

[jmbejar]

I had problems using glimmerjs > 0.8 with the --web-component option. I've built the project and tested the component in a custom web page, but the component wasn't rendered.

I've found the blueprint was generating an index.ts file with the following line:

initializeCustomElements(app, { 'my-component': 'my-component' });

However, I had to manually change to the following to have the component working

initializeCustomElements(app, { 'my-component': 'MyComponent' });

This follows the changes made in the glimmer-web-component package (https://github.com/glimmerjs/glimmer-web-component/pull/22)
