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%

pre-commitフックのブランチカバレッジ設定から始め、既存のテストケースとともにGetCollectionクラスおよびGetCollectionFacetsクラスを調査してください。報告されたブランチカバレッジ0%を再現し、それらのブランチがカウントされない理由を特定し、必要なブランチカバレッジを95%に戻した後にフックが通ることを確認してください。
