Pull request #135: Bugfix/VECTO-1514 modeldata uses wrong inertia in case multiple ems are used on a position

Merge in VECTO/vecto-dev from VECTO/mq_vecto-dev:bugfix/VECTO-1514-modeldata-uses-wrong-inertia-in-case-multiple-ems-are-used-on-a-position to develop

* commit 'e0b13127':
  fix: correctly set inertia in em model data
  adding testcase to check model parameters of electric machine
