On source deletion, executions status stays running

[iporollo]

Description

If a source is deleted during an execution, the status of that execution stays running.

Expected behavior

When a source is deleted, the execution should be stopped (and probably removed).

Steps to reproduce

1. Add a data source
2. Wait until an execution is running
3. Delete the data source while an execution is running
4. Navigate to executions page
5. See error

We will need to hit the APScheduler API to stop an execution when a job is deleted.
