Fix NPE with lenient aggregators merging in segmentMetadata. (#15078)
When merging analyses, lenient merging sets unmergeable aggregators
to null. Merging such a null aggregator record into a nonnull record
would potentially lead to NPE in getMergingFactory.

The new code only calls getMergingFactory if both the old and new
aggregators are nonnull; else, if either is null, then the merged
aggregator is also set to null.
