unbalanced models: empty array of unused connector yields equations

Description

I found another source for unbalanced fluid models.

We have an empty array of

Modelica.Fluid.Vessels.BaseClasses.VesselFluidPorts_a topPorts[0]

nevertheless we get an equation

topPorts[0].m_flow = 0.0

which consequently gives an unbalanced model, since the empty array does not provide any variables.
Simple Testmodels are attached
