SONAR-6315 no indexing active rules in MassRegisterQualityProfiles

there is no need to index active rules at all during registration of Quality Profile as only deactivation changes trigger changes in the Active Rule index and registering quality profiles only activates active rules
removal of this indexing in RegisterQualityProfiles can't be done now as it requires to make initial indexing of Active Rule index when it doesn't exist be handled by another piece of code
