Paweł Dziepak 6a0ee5dbbf Merge "Simpler fix for the memtable reader's fragment monotonicity violation" from Botond ...

"
Recently it was discovered that the memtable reader
(partition_snapshot_reader to be more precise) can violate mutation
fragment monotonicity, by remitting range tombstones when those overlap
with more than one ck range of the partition slice.
This was fixed by 7049cd9, however after that fix was merged a much
simpler fix was proposed by Tomek, one that doesn't involve nearly as
much changes to the partition snapshot reader and hences poses less risk
of breaking it.
This mini-series reverts the previous fix, then applies the new, simpler
one.
