Fix branch test coverage in classes with 0% coverage and restore branch expected coverage back to 95%

The pre-commit hook was failing because it expected 95% branch coverage, but certain classes (GetCollection and GetCollectionFacets) were showing 0% branch coverage, even though we have test cases that should cover these branches.

To temporarily resolve this issue, we lowered the required branch coverage to 90% for the pre-commit hook to pass. However, we need to investigate the cause of this discrepancy, fix the issue, and restore the required branch coverage back to 95%

Iniziate dalla configurazione della branch coverage dell'hook pre-commit ed esaminate le classi GetCollection e GetCollectionFacets insieme ai relativi casi di test esistenti. Riproducete la branch coverage dello 0% segnalata, individuate il motivo per cui quei branch non vengono conteggiati e verificate che l'hook abbia esito positivo dopo aver ripristinato al 95% la branch coverage richiesta.
