Fix ESLint warnings using 'yarn lint --fix'

Summary:
Hi! I would like to contribute to React Native, and I am just starting out. I forked the repo and found that it has quite a lot of ESLint warnings – many of which were automatically fixable. This PR is simply the result of running `yarn lint --fix` from the root folder.

Most changes are removing trailing spaces from comments.

Haven't really done any manual testing, since I haven't done any code changes manually. `yarn test` runs fine, `yarn flow` runs fine, `yarn prettier` is satisfied.
