Dolphin unit test refactoring

This commit changes mainly two things:
1. The functionality related to the handling of temporary files and
folders is moved to a new class TestDir.
2. The setup of a temporary folder and of DolphinView instances is
now done in each unit test function. A benefit of this change is that
there are no unwanted interactions between different unit test functions
any more. Moreover, different test functions could now share a test
folder more easily.

Additionally, the reference arguments of all functions are changed to
pointers for consistency.
