Subject: [PATCH] fix: guard against undefined return from sendFunction in
 push-to-talk

sendFunction (wrapping sendMessage) returns Promise<void>, so accessing
.id on the result throws a TypeError. Add a null check to skip setting
startReadingFromMessageId when the return value is undefined.

Fixes #3042, fixes #3011
