test(e2e): improve HooksRunner.spec (#825)

* test(HooksRunner): properly setup temp dir

* test(HooksRunner): faster & simpler project setup

This is possible since we don't need an installed platform anymore
since we have dropped Test#012. We also needed to stop using
`util.preProcessOptions` because that expects platforms too. However,
its usage was irrelevant for the tests anyway.

* test(HooksRunner): remove unused hooks

* test(HooksRunner): reduce number of fixture files

* test(HooksRunner): make hook fixtures executable

* test(HooksRunner): cleanup & clarify "nohooks" tests

This also groups all "nohooks" tests in one describe block.

* test(HooksRunner): move tests to suitable block

* test(HooksRunner): only pass options where needed

* test(HooksRunner): cleanup "event handler" tests

- proper common test setup
- improve test descriptions
- test what the descriptions say
- replace the two last tests with a useful one
