Phone number registration: `phone-number-regstration-finish` not working properly

[Technophilus]

When registering a phone number and providing a response, the bridge asks the user to send the response SMS from Apple directly to it. When this is done, it works as expected with registering the phone number with Apple. However, future invalid commands to the bridge helper bot are interpreted as invalid responses. Interestingly, if the phone number registration has expired, it logs in the chat Usage: register-phone-number-finish <sms_response>. See the attached image:

This issue is considered resolved if there is a consistent response from the bridge when registering a phone number and either the register-phone-number-finish command is used and expected, or removed.
