Apollo Blockchain 1.50.35 Release (H2 block timestamp index fix) pr#1…

…212/stage

Merge pull request #1212 from ApolloFoundation/stage
Add alternative block_timestamp_idx with DESC sort to speedup blockchain sync due to long last block lookup statement exection on popOff operation: SELECT * FROM block WHERE next_block_id <> 0 OR next_block_id IS NULL ORDER BY timestamp DESC LIMIT 1
Original block_timestamp_idx is not deleted since deletion works differently for o-db initialization and existing db migration (require different statements)
Bump version to 1.50.35
Fully compatible with 1.50.34 reverted release
