Testnet stuck with 8/10 validators online and on the latest wallet version #277

🐛 Bug

We're already 4 days on block 244,322 with 8 validators connected (v2.1.x) and view=0.

Looks like in pre_commit some validator rejects block. Validate 7 approvals, Pre-commit 6 approvals. Also i see some "On new_view" messages in the log, but it actually never changes and looks like turn never goes to the next validator.

Test network was fixed on 22 October.

Block 244,322 (08 October) https://testnet.semux.info/explorer/block/244322 Block 244,323 (22 October) https://testnet.semux.info/explorer/block/244323

That block also included one 2 weeks old transaction. Before Testnet got unstuck, validators were voting for 2 competing chains with the different block hashes:

Also, while the primary validator was testgost111, all the further turns within 2 weeks took backup validator semux02 and he never passed the turn, neither increased the view within 2 weeks.

I think we should destroy the testnet for now:

And we can alway come back if a strong demand arises.
