Edit command with no changes made is still considered valid

[Tanishq4331]

Steps to replicate:

1. addclass cn/CS2103T ct/MON 09:30-11:30 r/70 l/Nex Tuition Center
2. editclass 1 ct/MON 09:30-11:30

This shows a success message even though no class details have been changed.

Expected:

The user should be warned that they have not made any changes to their class.

Their Response to the 'Original' Bug

[This is the team's response to the above 'original' bug]

It is very unlikely that the user will edit without changing anything. Also, it does not cause much inconvenience if it throws an error, because even if the user edits it to the same information, it still does what it is supposed to do. Thus, we feel that it should be severity.Low instead of Medium.
