  [GStreamer] Fix a crash for fast/speechsynthesis/speech-synthesis-real-client-version.html
https://bugs.webkit.org/show_bug.cgi?id=251056

Reviewed by Xabier Rodriguez-Calvar.

The crash happens when the web content does not specify a voice to use. We handle a null pointer
of the voice with the default voice.
