avoid SI-NaN/infinity value in shift strategy

  fix after merge conflict

Merge in VECTO/vecto-dev from VECTO/mq_vecto-dev:internal/bussimulations_Roeck to develop

* commit 'e9b995a5':
  in case even the third attempt searching an operating point for AT transmission in converter gear does not result in a valid operating point, allow a slight overshooting of the target speed.
  stay a little below max torque when using fixed operating point, in case search abortet, use fixed operating point for TC
  do not downshift if already in first gear (AT gearbox)

  removed P1 Bus Hybrid Roeck Testcases
  reverted Delaunay Map again to previous implementation
  replaced all [Test] attributes by [TestCase]
  added delta for double comparisons in test cases
  added missing files for tests
  reverted Sum Method back to previous behavior (returning Null if the source was empty)
  replace all [TestCase] attributes by [Test] (has different visualisation in testrunner)
  Moved CyclesCache to DeclarationData
  DefaultDriverStrategy CoastingForce: uses correct engine and the correct internalvoltage from the battery, adds up drag from combustion and electric
  corrected error with AddRuns returning integers now
  BusAuxiliaries removed comment
  Alternator: restore previous version (unchanged)
  Removed setting LastAccessTime
  AddRuns returns the RunIdentifiers again (not the run object)
  removed testcase for QuadraticEquationFit - not implemented anymore
  ModalDataContainer ElectricMotorEfficiencyGenerate revert back to old version
  VectoMath removed FitQuadraticEquation
  DriveDistance: renamed variable for debug
  CompletedBusFactorMethodTests cannot be run in parallel (out-of-memory)
  DefaultDriverStrategy: container cannot be null, therefore null-coalescing is not needed.

DefaultDriverStrategy CoastingForce: uses correct engine and the correct internalvoltage from the battery, adds up drag from combustion and electric

in case even the third attempt searching an operating point for AT transmission in converter gear does not result in a valid operating point, allow a slight overshooting of the target speed.

in case search abortet, use fixed operating point for TC

added new testcase J for E4; reduced engines to 2 again; updated drag torque curve to a more realistic one
