Snapshot generator: corrected cardinality of element with a derived type

[marcovisserFurore]

Description

When you were using a profile with an element that has again a profiled type. then the snapshot generator used the cardinality of that profiled type, and not the cardinality of the element. So

For example when you profile the element Observation.code and you use a derived type for this element, for example CodeableConceptProfile, then the cardinality of CodeableConceptProfile was used for the element Observation.code. In this case the minimum cardinality of Observation.code went from 1 to 0, which is incorrect. This has been solved in this PR.
