Title: 198 sub requests for unscheduled shifts

Added validation in the model to ensure a shift is scheduled before a sub request can be made for it. Also added a check in the controller to prevent a user from trying to render the sub_request form if the soon to be associated shift is not scheduled (necessary because the form uses the shift to set many default fields)
