Fix error filtering in race condition test

alexey-milovidov · claude · alexey-milovidov · commit 2d5df63c63b6 · 2026-01-25T19:46:15.000+01:00
The `filter_expected_errors` function was not properly filtering all expected
errors during the race condition:

1. "UNKNOWN_TABLE" didn't match the actual error message "Unknown table
   expression identifier" - changed to "Unknown table"
2. Code 279 errors (`ALL_CONNECTION_TRIES_FAILED`) were not filtered at all -
   added filters for "All connection tries failed" and "connect to any replica"
