The attempt_threshold option in sentry-sidekiq will silently drop jobs with low retry count #2939

Problem Statement

The attempt_threshold (added in #2503) has a bug when a job's retry option is lower than its attempt_threshold (e.g. retry: 1 with attempt_threshold: 3).

In those cases the error handler skipped every attempt and the job was silently dropped.
