Mark Thomas 5c95bf6be2 mutation_store: make separate requests by primordial and successor ... Summary: D22206317 (9a6ed4b6ca) added requesting of predecessor information for suspected primordials by the successor ID. This allows recovery of earlier predecessors when partial data upload resulted in the history of a commit being extended backwards. Unfortunately, while the individual requests are fast, the combined request using `OR` in SQL ended up being very slow for some requests. Separate out the requests at the application level, and aggregate the results by concatenating them. `collect_entries` already handles duplicates should any arise. Most of the time the successor query will very quickly return no rows, as it only matters when history is extended backwards, which is expected to be rare.
