Channel cache prepend can fail for some seq, validFrom combinations #3872
There are scenarios where a view query incorrectly fails to prepend its results to the channel cache. These don't appear to be related to the prepend changes in #3475 - these scenarios are also failing to prepend the cache in 1.5.1.
Cause: Query results aren't prepended to the cache because the high sequence value in the query results is lower than the cache validFrom, and the non-zero limit marks the request as non-open-ended.
Cause: Query results aren't prepended to the cache because sequence m isn't included in query results, and so there's no overlap.
Cause: Second changes query doesn't prepend to the cache because there's no overlap (sequence m isn't in the channel, cache isn't in the result set
