Subject: Clear metadata provider cache when provider parts are registered

AddParts replaces _metadataProviders but left _metadataProviderCache
holding provider arrays from the previous registration. Invalidate the
cache so repeated AddParts calls cannot serve stale providers, and give
the previously uncalled ClearMetadataProviderCache its intended caller.
