Success message generated instead of error message when wrong name provided for edit-task feature

[nus-pe-bot]

Using edit-task to edit a task with student Roy Balakrishnan assigned to it. If the following command is provided: edit-task 3 deleteStu/Roy or edit-task 3 deleteStu/roy Then no person is deleted as mentioned in UG since command is case sensitive But it does not display error message when executed, it instead generates a success message that the task has been edited. No change is made to task however.
