Add correlation id to all sentry errors

What does this MR do?

Before this, we were only adding the correlation id to the "acceptable exceptions" which we handle in code.

But we need to add it to the default raven context so the information would be available for uncaught exceptions.

Does this MR meet the acceptance criteria?
