Fix getApplicationSubAllFlatEntityMaps to prune unrelated appIds universal identifier aggregators (#21234)

# Introduction
Atm when computing the `fromAllFlatEntityMaps` we're retrieving all the
applicationIds related metadata entities to build a flat entity maps
scoped to them ( atm always the applicationId + twenty-standard
application id ) only inter app dependency we manage for the moment

A flat entity contains universal identifier aggregator to its related
entities

The issue was that the `getApplicationSubAllFlatEntityMaps` wasn't
pruning the aggregator by app

Now added a new process phase after the initial one that will check that
all the aggregators contains universal identifiers that has been
retrieve from the appId + appId standard intersection

## TDD test
Created a very human readable ( that's a joke ) test
