This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_3_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2) |

PR description:
This is a fix to #32076 that introduced a crash in NANOAOD workflows.
For the record, the crash only happens when running the NANO step alone, but is not visible when both NANO and DQM:@nanoAODDQM steps are run (hence why it wasn't spotted earlier).
The fix consists to rearrange the order of some modules.
In addition, it was noticed that some booleans were not properly set for MC when recreating the jet PUPPI collection. This is now corrected.
Finally, the V15 PUPPI was in fact NOT enabled in the previous PR for reNANOAOD since only the run2_miniAOD_UL modifier was considered. This is also corrected. (That last item is not a backport because V15 is run by default in master)
PR validation:
The two following commands (used in NANOAOD v8 validation and that previously failed) are now running fine.

The PUPPIMET is indeed different when running this command on 10_6_19 and on 10_6_19_patch1 with this PR added.
It is identical when the commands above are run without the run2_nanoAOD_106Xv1 modifier.
