Tolgee throws 500 on coinstraint violations

[JanCizmar]

Describe the bug
When user executes API endpoints too fast, it can lead to constraint violation errors from the database level. We should check all the past errors and retry such operation before the transaction is started.

Maybe some kind of @RetriableTransaction annotation can be invented for this, so we don't have to handle it manually.

For Tolgee team
