fix(flaky): ignore false positive exception
Summary
- fix(flaky): ignore false positive exception
- Currently we use Retriable for handling flaky sql tests (temporary solution). If our sql query succeeded but on client the timeout was raised, Retriable will execute the query again. This may lead to situation, when we will get an error for violating unique index. This commit ignores this error
- Close #786 (closed)
- Cherry-pick to: none
- Docs follow-up: not necessary
