After repeating an add command with duplicate name, I'm unable to complete the field

[nus-pe-bot]

After I entered the first duplicate input, it constantly throws "This person already exists in ORGANice" even though I changed the name to n/asdasd which clearly does not exist yet

This is clearly user error as ic/NRIC needs to be changed as that is the primary key, changing n/NAME is irrelevant.

@C-likethis123 could you check whether the documentation is clear on this? Specifically add and detecting duplicates

[C-likethis123]

On 'detecting duplicates': the definition of a duplicate is clearly stated.
However I can see how it is unclear that an attempt to add a duplicate will be rejected by ORGANice. Also, the 'detecting duplicate' portion of the user guide could be placed in the 'add' command for more clarity.

I also suggest a change in the error message: to prompt the user to change the NRIC given.
