Speed up tests (blue-yonder#308)

* Speed up tests by using less statistics

* Only run full tests on master (not on PRs)

* Check for master

* better use if here

* As we run everything with the if, we only have to do one stage

* Changed the role of one of the tests

* Do not check examples for coverage

* Enable full build on PRs

* Only use one line for the command

* Simplify condition
