RuntimeQuery::filter() now returns null when the query doesn't match,
instead of an empty array. This distinguishes between "no match" and
"match with empty payload", fixing the issue where subscriptions with
empty payloads weren't being delivered.
Updated Realtime::getSubscribers() to check for null instead of using
!empty(), and updated all tests to expect null for non-matches.

- Add missing isSelectAll() method to RuntimeQuery class
- Update RuntimeQueryTest to use compile() before filter() since filter()
expects pre-compiled query arrays, not Query objects
- Remove incorrect break statement in Realtime::getSubscribers() that was
stopping iteration after the first matching channel, causing subscribers
to not be found for subsequent channels
- Use local variable $subscriptionsByChannel to avoid unused variable warning
