[qa] Correct the checkpoint for first post-UAHF block for testnet3
Summary
This is a follow-up to MR !1539 (merged) which corrected the UAHF checkpoint block for mainnet. This does similar for testnet3. The old checkpoints don't matter much now since we have since added more checkpoints after them, but it's nice to be correct and consistent. This is a purely aesthetic/QA MR.
Test plan
- ninja check-all
- Use a block explorer or full node testnet3 RPCs to verify that
the existing hash for height 1155875 is
00000000f17c850672894b9a75b63a1e72830bbd5f4c8889b5c1a80e7faef138
on both BTC & BCH chains (this is wrong as a checkpoint!). - Use a block explorer or full node testnet3 node RPCs to verify that
the new hash in this MR for height 1155876 is
00000000000e38fef93ed9582a7df43815d5c2ba9fd37ef70c9a0ea4a285b8f5
and that this block exists only on BCH and not on BTC.
