Add phase currents to comparisonSignals.txt to consistently cover zero sequence currents (#3497)
* Replaced zero sequence currents from comparison signals by meaningful phase currents
* Signals are covered by aims.idq_rr[1] and aims.idq_rr[2] Instance name aimc should have been aims
* Zero sequence currents are not included in space phasors Therefore the phase currents of the stator and rotor have to be added to comparisonSignals.txt
* Add phase currents to comparisonSignals.txt of Modelica.Electrical.Machines.Examples.InductionMachines
* Add phase currents to comparisonSignals.txt of Modelica.Electrical.Machines.Examples.SynchronousMachines
* Add phase currents to comparisonSignals.txt of Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.InductionMachines
* Add phase currents to comparisonSignals.txt of Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SynchronousMachines
