Check if processed data already exists in --production mode (#1024)

* Add check if live_data exists, assuming live_data first type

* Check now for bootstrax_state instead. Not sure about the 'else' in l.362.

* Removed 'else' statement

* Update bin/bootstrax -> typos

* Change 'processing' to 'busy' in possible bootstrax_states
