addressbook.json only contains contacts you have added, but there are other contacts in the app.

Description of the bug:
This could be a follow up to one of the previous bug reports that I reported on. It is related to the prof -a command I entered previously. My addressbook.json file only shows contacts that I manually added with the add command. Keep in mind I am unable to see anything in the contact list in the UI as mentioned previously in one of the bug reports. So I was unaware that there were many contacts that might be in the app. For example, I typed delete 20 and a contact was deleted that I was unaware that it existed. I opened up the addressbook.json and it still has the same contacts that I manually added previously.

Steps to recreate the bug:

1. type prof -a (from previous command I executed)
2. Open up addressbook.json (previously opened as well)
3. type delete 20
4. Message success: Deleted Person: Stephane BRESSAN; Phone: 65163543; Email: null; Address: COM1-03-20; Tags: [Associate_Professor_Educator_Track][SOC_faculty]
5. Open up addressbook.json
