## Title
Job j_5f2a0c runs twice after ORB-1101 LeaseExpired on the reports queue
## Component
core
## Orbit version
3.2.1
## Error codes
ORB-1101 LeaseExpired
## Steps to reproduce
1. Run `orbit worker --queue reports --concurrency 4`.
2. Enqueue a `generate_statement` job that runs longer than 300 s.
## Expected
The job runs once.
## Actual
The lease expires at 300 s and worker w-b7 starts the same job again (attempt=1).
