Add command does not allow students with same name

[nus-se-script]

Given context of an education institute in Singapore, it is common for students to have the same name e.g. Ryan Tan or Alex Yeoh. Add command does not allow such duplicate names even with different tags associated which may be counter-intuitive to teachers using StoreClass.
