Chain building in certificate validation

Hi,

I'm using certvalidator 0.11.1.

It cannot build a chain with the attached certificates for the one in me.der.
However, it should work, as the chain was extracted from a Windows tools that examines certificate chains.
me.zip

The traceback gives:
File "/usr/local/lib/python3.8/site-packages/certvalidator/init.py", line 193, in validate_usage
self._validate_path()
File "/usr/local/lib/python3.8/site-packages/certvalidator/init.py", line 108, in _validate_path
paths = self._context.certificate_registry.build_paths(self._certificate)
File "/usr/local/lib/python3.8/site-packages/certvalidator/registry.py", line 314, in build_paths
raise PathBuildingError(pretty_message(
certvalidator.errors.PathBuildingError: Unable to build a validation path for the certificate "Common Name: ANDRÉ VENTURA DA CRUZ MARNÔTO ZÚQUETE; Serial Number: BI068540477; Given Name: ANDRÉ; Surname: VENTURA DA CRUZ MARNÔTO ZÚQUETE; Organizational Unit: Cidadão Português, Assinatura Qualificada do Cidadão; Organization: Cartão de Cidadão; Country: PT" - no issuer matching "Common Name: ECRaizEstado 002, Organization: Sistema de Certificação Eletrónica do Estado, Country: PT" was found

Start by reproducing the report with the certificates in me.zip using certvalidator 0.11.1. Trace validation from certvalidator/init.py through _validate_path() into registry.py and its build_paths() method. Done means the supplied certificate chain builds successfully and no PathBuildingError is raised.
