Fix addOnTests by removing --magField (93X)
Based on CMSSW_9_3_X_2017-07-09-2300
Integration of #19469 requires to remove the hardwired --magField parameter as used in the addOnTests as it points to deprecated field versions. The default from Configuration/StandardSequences/python/MagneticField_cff.py will be used instead.

It would make sense to fix this also in past release series where possible. The fix is proper for any release since 7_4_3.
