/**
 * This script is used to remove a linked third party identity from a user account.
 *
 * Parameters:
 *  --providerId: the third party identity provider (e.g. google, collabratec)
 *  --userId: the id of the user
 *  --commit: if present, the script will commit the changes to the database.
 *
 * Usage:
 *
 *   - dry run:
 *     node scripts/unlink_third_party_id.js --providerId=google --userId=${SOME_USER_ID}
 *   - commit:
 *     node scripts/unlink_third_party_id.js --providerId=google --userId=${SOME_USER_ID} --commit
