Remove redundant resolveHostMetadata() calls from tests

resolve() internally calls tryResolveHostMetadata() which already
populates resolvedHostType. Remove the redundant explicit calls
and revert to single fixtures, except for
testResolveHostMetadataDoesNotOverwriteExistingHostType which
genuinely needs a second call to verify no-overwrite behavior.
