Requirement matchers returned in collection of the same class are evaluated as in OR relation

[odockal]

More than one requirement matcher of the same class returned in collection in RequirementRestriction annotated method are evaluated as in OR relation. Thus, there is more configurations returned than it should from cartesian product of requirement combination. In this line, code is iterating over each passed requirement, but it should be grouped by configuration class of the requirement and tested whether all attributes of requirement matcher fulfills the condition.
