[13_2_X] Fix random DQM path order from ConfigBuilder in case of duplicate DQM sequences

[makortel]

PR description:

Backport of #42833. Original description

PromptReco for Heavy Ions was generating different RECO configurations for each job of the same Primary Dataset (and Run). This caused problems during merging as the ParameterSet registry grew, as reported in https://cms-talk.web.cern.ch/t/high-memory-usage-in-merge-alcareco-job-for-promptreco-run373536-zerobias17/29655.

The difference between the RECO configurations was in how the DQM sequences were assigned to DQM Paths. One source for random shuffling was found to be in ConfigBuilder in case the expansion of the DQM sequence specifier leads to duplicate sequences.

This PR fixes the path ordering, and adds a test for it.

PR validation:

The added unit test succeeds (and failed without the fix)
