Fixed name look-up bug Modelica.Electrical.MultiPhase.Examples.TestSensors:
In the model an instance of class "Blocks.Sources.RealExpression realExpression"
is defined. However, in the hierarchy up to Modelica there is another package "Blocks"
and therefore a tool finds the wrong package in which realExpression is not present.
Fixed this by changing the class name to "Modelica.Blocks.Sources.RealExpression realExpression"
