Remove sorting parameter from ConfigurationSessionTestSuite #903

The ConfigurationSessionTestSuite sorts the test methods by default. A
field identifies whether sorting is activated, but the field cannot even
be set but is always true. So, this parameterization is completely
obsolete and only introduces unnecessary complexity to the session test
framework.
