Extra Parameters in Call Update

Issue Summary

Extra parameters are being sent along in my Call Updates — in particular, StatusCallbackMethod, Method, and FallbackMethod are all being sent to Twilio with the values of "POST" even though I didn't specify them in my actual calls(id).update( ... ) call.

This wouldn't be a big deal except that I think by specifying the method for any of these endpoints, the actual URL stored for them gets reset. So my incoming calls, which had a Status Callback URL set by the TwiML App assigned to that phone number, were having their Status Callback URLs reset any time I used the Call Update API.

Steps to Reproduce

1. Start a call
2. Update it from the Ruby client

Code Snippet

# Example for ending a call from the server

Twilio::REST::Client.new.calls(twilio_call_sid).update(
  status: :completed
)

Exception/Log

Completed parameter was sent but so were the other parameters.

Technical details:

• twilio-ruby version: 6.7.1
• ruby version: 3.2.2

(Twilio Ticket 15197987)

Start at the Ruby client's calls(...).update entry point and inspect how update parameters are assembled. Reproduce the request with status: :completed, then verify that only explicitly supplied parameters are sent and existing callback URLs are not reset.
