Fix build server

Refactoring the behaviour how to start the backend process. Instead of
node's rather unreliable `spawn` let's use shell commands in package.json.

Also take `yarn run eslint` out of `yarn run test` and run it separately
on travis. If possible, try to separate scripts on Travis for
error friendliness. Only for coverage we need to combine the `yarn run
cucumber` and `yarn run mocha` in one script `test`.
