build: Update devDependencies

* karma-coverage@0.3.0: Includes fix for karma-runner/karma-coverage#24.
  We can remove the workaround config in text-console that was
  there to prevent an unwanted directory from being created.

* karma-chrome-launcher@0.1.8: Includes support for "chromium-browser"
  (in addition to "chromium") so we can eventually remove the hack
  in Jenkins that exports CHROME_BIN=chromium-browser.
