Paweł Dziepak 5f08831192 streamed_mutation: fix reversing range tombstones ...

Right now reversed streamed mutation emits range tombstones after the
mutation fragments affected by them. This breakes the queries.

This patch reworks the way range tombstones are handled in reversed
streams:
 - range tombstones are no longer flipped -- invariant that start bound
   is smaller than the end bound always holds
 - in reversed streams they are ordered by their end_position()

Fixes #2982.
