fix(integrations): Check retries_left before capturing exception (#3803)

Since rq/rq#1964 the job status is set to Failed before the handler decides whether to capture or not the exception while handle_job_failure has not yet been called so the job is not yet re-scheduled leading to all exceptions getting captured in RQ version >= 2.0.

Related to #1076
Fixes #3707
