This ticket is to add test coverage for this assertion in ShardingCatalogManager::checkChunkMatchesRequest.

It could be done through a unit test or integration test. We have unit these two related unit test files:

https://github.com/mongodb/mongo/blob/master/src/mongo/db/s/config/sharding_catalog_manager_split_chunk_test.cpp

https://github.com/mongodb/mongo/blob/master/src/mongo/db/s/config/sharding_catalog_manager_merge_chunks_test.cpp

that call methods on ShardingCatalogManager, so it might make sense to create an analogous sharding_catalog_manager_move_chunks_test.cpp.

Alternatively, it could be tested in an integration test by directly sending commitChunkMigration to the config server without a ChunkVersion when the config server is in FCV 4.4. See this class that represents a commiitChunkMigration request.
