Reset timed triggers check for when developing to avoid timeout of worker

[GDay]

When a dev has not used their environment for a while, the timed_triggers function will take a long time to complete. Potentially timing out the task.

To avoid this, there is a command now, which will run when supervisor starts to reset the last check field to now. This will only work for the development setup, obviously not on production as it could skip tasks.
