chore: key cleanup

[arshadali172]

Problem

Closes https://github.com/datagovsg/formsg-private/issues/8

Solution

• Include script for removing dangling keys in login, user, feedback and submission collection. Refer to the issue for how these keys were identified
• Include script for migrating emails in forms collection from comma-separated string of emails to array of emails
• Coerce email string into email array before saving into database as this has caused issues in the past

Notes

• Coercion of email string into email array on the frontend or backend controller level is not that straightforward as there are multiple places that need to be changed (create/duplicate/edit for the backend and create/edit for the frontend). Editing on the mongoose level seemed the most straightforward given that frontend changes will take a while to propagate and the frontend is to be re-written

Tests

• Can submit email mode form with 1 email
• Can submit email model form with multiple emails (create form flow)
• Can submit email model form with multiple emails (edit form flow)
• Can submit email model form with multiple emails (duplicate form flow)
• Can submit email model form with multiple emails (template form flow)

recipientEmails is the submission collection faces similar issues as emails in the form collection. Should we edit this too?

may i request for one last cleanup, and that is to rename all the folders in scripts/ to prepend the date that they were introduced into the codebase? e.g. 20200917_unused_key_cleanup
