Make test gpio control work again (#2034)

* Made test_gpio_control work again

* Test configuration file had still `functionCallDown` and `functionCallUp` as function calls instead of newer `functionCall1` and `functionCall2`
* Made path of config file relative to the location from where the imports work (and the test is executed which is `./components/gpio_control/`

* Mocked function os.system in test_gpio_control

* Test didn't finished without this setting since os.system is used to check if a phoniebox service is running on the machine which may not run on machines this unit tests run on
