Wrapped primitives do not use origin primitive

[Mixermachine]

When we generate a wrapped primitive, we expect that the wrapped primitive uses the primitive internaly.
Currently the providerMap of the TestDataStatics class holds Null values for wrapped primitives (e.g. java.lang.Float, java.lang.Double, ...).

The generation still works, because the later stages of the generation use a best effort approach to then fill the wrapped primitive, but this no longer guarantees the value equivalence between for example java.lang.Double and double.
