fixed race condition when running tests
sometimes the test run before the http server was ready, which caused timouts
corrected the relative require pathes (uses __dirname now)
added travis mongodb dependency
the test users are now added to the database in the correct order
added log entry to debug travis errors
fixed invalid logfmt call
added assertion for test users
refactored runOptions for the app

the before-tests did not run after the changes introduced in 3d9f0935628b3e816d47e87e09a663c7888e7fb2
