containedIn() only checked that the other index declared the same field
keys, never that they held the same values, contradicting its documented
contract of containment "with the same value".
Dht::query() uses containedIn() to deduplicate projected results. Because
every result of a given query shares the same projection schema, any two
results compared equal: the first one suppressed all the later ones, and the
"lesser" branch even erased the already reported result. A query selecting a
field therefore reported a single value regardless of how many matched.
Compare the FieldValue as well, and add a regression covering distinct
values, equal indexes and a narrower projection contained in a wider one.

Cover Value::toJson() / Value(const Json::Value&) preservation of the
pushType field, and its absence from the JSON when empty. This is the
serialization path used by DhtProxyClient::put(), so mobile clients
behind a DHT proxy depend on it to propagate the push notification
type.
