tests: fix logged panics in reproducible labels test

[algorandskiy]

Summary

Forked ledgers have not preserved protocol so that we logged errors from voters tracker.
Set logging level=info in tests that produce to much debug output while adding thousands of blocks.
Fixed onlineTotals call in checkUpdates for non-sense input values

Why is it not a problem that the panics are being made, and we can just suppress the logs?

[algorandskiy]

Panics are in in level=panic, and this is fixed in fork() function as the PR description says.
The logs are for ledger.AddValidatedBlock messages when we add thousands of blocks in a test
