Build and run app separately

[janpio]

Currently the app is built differently depending on wether you run the tests locally or on SauceLabs. This makes it more difficult to understand what is going on.

Suggestion: Use run -nobuild to run the app (locally), and always build separately and in its own step.

Note: Appium tests also rebuild the app again, because they do some changes.

#173 splits the build and run for the normal tests, so the build is identical for both local and SauceLabs runs.
