Duplicates allowed if added spacing in between names

[sarahteonin]

Description Extra spacings between names are considered as different students. Perhaps a check to ensure that these spacings are not allowed would be good to prevent duplicates.

Steps to Reproduce add n/john doe p/222 e/3@gmaiul.com add n/john doe p/222 e/3@gmaiul.com (there's an extra spacing in between john doe in the second line)

Expected Behaviour Duplicate identified

Actual Behaviour Student added

Reason for Severity Duplicates are allowed in the app
