Import React by default in `connect create` template

[chsmc-stripe]

I get a warning in my editor when using JSX without React being imported. Not sure if this is an "everyone" thing or a "my company" thing but thought I'd open a PR to start a discussion about whether it should be in the default template.

Yep, ran into this as well

Thank you for your interest in contributing to this project! However, we are in the early stages of the development of Code Connect and not ready to accept external contributions through PRs yet.

Closing the PR now as we included a fix for this in 0.1.1.
