Incorrect error message for `module list`

[cx0810]

Error message for module list displayed is problematic. When user inputs wrong format for module list, the error message displayed is module list: Adds a module to the timetable.... Instead, it should be module list: Displays contacts of a module...

Team's Response

This is an legitimate bug, need to change the error message but it is unlikely to largely effect the users usage of the module as the correct explanation is given in the user guide.
