chore: fix travis build (#5627)

Disable running tests in Firefox on Travis for regular PRs as it wasn't the case previously and is broken for some reason. We'll follow up in the future in #5626.

Update .travis.yml based on their latest infrastructure and new npm caching method.

Silence logging of sourceset test sources.

Closes #5616
