sum-data contains wrong output for fuel type (class name of iterator) instead of fuel string. add to testcase

Added missing files for tests again (TestFullCycleModDataIntegrityDecl_P1ESS, and TestFullCycleModDataIntegrityDeclESS)

PowertrainBuilder DummyEngineInfo CombustionEngineOn: Set default again to false (was wrongly reverted in 6529a9e5)

adapt PCC tests due to different gearshift behavior (the HEV jobs still used the 'old' AMT shift logic to compute the shift polygons)

Added Case for APTN for ResponseUnderload in DrivingActionBrake to try again searching a suitable braking power.

additional rule in PEV shift strategy to avoid downshifts so that next operating point is beyond upshift line
fix: set thermal overload in testpowertrain

remove dividing SP power demand for technology "electric" by alternator efficiency as the lookup-table already contains mechanical power demand

update calculation of PEV shift polygon for downshifts. introduce new parameter to adapt shift lines

Added that HybridStrategy does not use VelocityDropData if its not valid (like in APT-N gearboxes: they have no traction interruption)
