Application does not parse user input for module code correctly

[nshian]

When the user enters in the module code, they may accidentally enter an additional "/" after the "m/" field before entering the actual module code. However, the application is unable to handle this invalid user input and incorrectly accepts the module code to be "/CS1010" instead of printing an appropriate error message.
