test: flatten tests (puppeteer#2337)

Today, we have tests split into multiple files, with files pulling
tests from some other files.

This patch starts explicitly gathering all tests from the same
`test.js` file.

Drive-By: move one test from `browser.spec.js` into `puppeteer.spec.js`
since it starts browser itself.
