Extract createStudentCheckin and endStudentCheckin

This issue rescues code from unmergable PR 465

Add the following methods to automate Checkin timestamp and duration creation:

(Code for PR 465's CheckinService available here)

    @Transactional
    public Checkin createStudentCheckin(Long studentId) {
        Instant now = Instant.now();
//      Prevents accidental opening of multiple check-ins
        if(checkinRepo.findByStudentIdAndCheckoutTimeIsNull(studentId).isPresent()){
            System.out.println("Unclosed Checkin Found for Student with ID: " + studentId);
            endStudentCheckin(studentId);
        }

        System.out.println("Creating Checkin for Student with ID: " + studentId);
        Checkin newCheckin = new Checkin();
        Student existingStudent = studentRepo.findById(studentId)
                .orElseThrow(() -> new EntityNotFoundException("Student not found with id: " + studentId));
        newCheckin.setStudent(existingStudent);
        newCheckin.setStartTime(now);
        checkinRepo.save(setCheckinTypeByDayHour(now, newCheckin));
        existingStudent.getCheckin().add(newCheckin);
        studentRepo.save(existingStudent);
        return newCheckin;
    }
    @Transactional
    public Checkin endStudentCheckin(Long studentId) {
        Instant now = Instant.now();
        System.out.println("Creating Checkout for Student with ID: " + studentId);
        Student existingStudent = studentRepo.findById(studentId)
                .orElseThrow(() -> new EntityNotFoundException(
                        "Student not found with id: " + studentId));
        Checkin unclosedCheckin = checkinRepo.findByStudentIdAndCheckoutTimeIsNull(studentId)
                .orElseThrow(() -> new EntityNotFoundException(
                        "Unclosed Check-in not found for student with id: " + studentId));
        unclosedCheckin.setEndTime(now);
        checkinRepo.save(unclosedCheckin);
        BigInteger oneHourInSeconds = BigInteger.valueOf(3600);
        //Sets max checkin time to 1 hour:
        if(unclosedCheckin.getTimeInClassInSeconds().compareTo(oneHourInSeconds) > 0){
            unclosedCheckin.setTimeInClassInSeconds(oneHourInSeconds);
        }
        existingStudent.getCheckin().add(unclosedCheckin);
        System.out.println("Service: Saving finished checkin with ID: " + unclosedCheckin.getId());
        return unclosedCheckin;
    }

Notes:

• Parameters that accept studentId may have to be changed to studentUid.
• Following the close of this issue, we may want to add setCheckinTypeByDayHour (also in PR 465's CheckinService), which automates the setting of CodingType.
