Remove unused reports

[ajkiessl]

We have reports in the code like 'final_submission_approved_report' and 'committee_report'. I don't think these are being used. Confirm if we can remove these and then remove if we can.

Remove from: views, controllers, routes

The 'final_submission_approved_report' can be removed since it is not being displayed anymore. We need to check with the partners to see if they still want the 'committee_report'.
