tests: Resolve Gateway timeout during automated tests by adding delay after minify request

* Remove npm cache from Travis, this was causing a world of pain.
* Remove the broken line attribute tests.
* Do a HTTP get against Etherpad to begin minification.
* Wait 10 seconds after minification before running tests.
