      Description

      The test global_snapshot_reads_downgrade_cluster.js fails when timestamp safe unique indexes are enabled.

      [js_test:global_snapshot_reads_downgrade_cluster] 2018-04-30T13:35:16.169+0000 c20277| 2018-04-30T13:35:16.169+0000 F -        [initandlisten] Fatal assertion 28579 UnsupportedFormat: Application metadata for table:index-17--7382423157972859957 has unsupported format version: 10. Index: {name: ns_1_min_1, ns: config.chunks} - version too new for this mongod. See http://dochub.mongodb.org/core/3.4-index-downgrade for detailed instructions on how to handle this error. at src/mongo/db/storage/wiredtiger/wiredtiger_index.cpp 268 

      It seems that it is required to recreate unique indexes in this test before binary downgrade.
