Rest resource response throws exception when sending sms inside the resouce

Problem

When creating a rest resource that sends an sms using the module, the following exception appears when receiving a response from the resource:

A fatal error occurred: The controller result claims to be providing relevant cache metadata, but leaked metadata was detected. Please ensure you are not rendering content too early. Returned object class: Drupal\\rest\\ResourceResponse.

Solution

Similarly to how #2630808: Response::getResponse() does not collect cacheability metadata from Url object → solved it, the Url generated should collect bubbleable metadata in SmsMessageProcessor::deliveryReportUrl().
