fix(mirror): forward the query value limit to both databases

Mirror hands every other piece of configuration to its source and
destination, but setMaxQueryValues only ever reached the wrapper. Reads
run against the source, so a caller that lowered the ceiling silently
kept querying at the old one, which is how the relationship value-limit
test found this on the Mirror lane alone.
