Incorrect error message

[nus-pe-script]

Describe the bug When logging in as an already-registered user, when I log in with the correct username but incorrect password, the message indicates that my username is not found in the system.

To Reproduce Steps to reproduce the behavior:

1. Type 'addUser uName/tristy uPass/pe2'
2. Type 'login uName/tristy uPass/pe'
3. See error

Expected behavior It should indicate that password is wrong instead of misleading user that his/her username is wrong when it is correct.
