The test built @marcxml and @oaidc expected data using metadata_record()
with no parameters, while the OAI server's get_biblio_marcxml() always
calls metadata_record({ interface => 'opac' }), which applies the
ViewPolicy filter. On nodes where the MARC framework has non-default
hidden values (or a stale cache entry), ViewPolicy strips fields like 245,
causing the expected and actual responses to diverge.
Fix by using interface => 'opac' when building the expected data, and
deriving dc:title from the filtered MARC record rather than hardcoding it,
so both sides of every comparison go through the same code path.
