refactor: Add extra logs to Client::send_call_notifications_if_needed

Also make it return `Result<bool>` instead of `Result<()>` so we can check if the event was sent.

 ### Features
 
+- `Client::send_call_notification_if_needed` now returns `Result<bool>` instead of `Result<()>` so we can check if
+  the event was sent.
 - Added `SendMediaUploadRequest` wrapper for `SendRequest`, which checks the size of the request to
   upload making sure it doesn't exceed the `m.upload.size` value that can be fetched through
   `Client::load_or_fetch_max_upload_size`.
