Generic pipe: Bug in conditional convection model

Describe the bug

This is related to parameter withConvection of model AixLib.Fluid.FixedResistances.GenericPipe.
If you "show component" genericPipe in the example AixLib.Fluid.FixedResistances.Examples.GenericPipe, you see that the component thermalPassthroughConvection is still there.

Expected behavior / Solution

The component should be conditionally removed.
Add if not thermalPassthroughConvection.
