Andres Notzli 1d20fa9d0f Fixed and simplified merge_helper ... Summary: MergeUntil was not reporting a success when merging an operand with a Value/Deletion despite the comments in MergeHelper and CompactionJob indicating otherwise. This lead to operands being written to the compaction output unnecessarily: M1 M2 M3 P M4 M5 --> (P+M1+M2+M3) M2 M3 M4 M5 (before the diff) M1 M2 M3 P M4 M5 --> (P+M1+M2+M3) M4 M5 (after the diff) In addition, the code handling Values/Deletion was basically identical. This patch unifies the code. Finally, this patch also adds testing for merge_helper.
