Martyn Inglis 59ab5da5d3 Handle errors where the notification isn't found when executing the tasks
- Thows a NoResultFound sqlalchemy exception
- Which causes a retry. This means we give it a few goes (5, max 5 hours)  for the notification to appear.
- Should never happen, only if we get some task overlaps that are unusual that leads to tasks executed in an overlapping nature.
