Given that it is for CS2100, the contact list should not accept 2 contacts of the same name (would be weird if there exists a student who is in both tutorial group T11-2 and A12-3) -> module restriction 1 tutorial per student.
Steps to reproduce
Launch the application
Run command uc 6 n/Irfan Ibrahim
Expected behavior
Duplicated person (name) in index 5
Actual behavior
Index 6 successfully change name to the same as Index 5
Reason for severity
Would inconveniences the TA if they were to see a student belonging to 2 tutorial group when NUS CS2100 only restricts 1 student 1 tutorial group.
Idea
When updating the contact, check whether the updated fields contacts duplicate with the other contacts.
