Failure when no fallback stt set

[builderjer]

If there is no fallback_module, the mycroft-speech.service fails to load.

I believe it has something to do with this:

ovos-core/mycroft/client/speech/listener.py

Lines 357 to 359 in 883bdac

	if not self.fallback_stt:
	clazz = self.get_fallback_stt()
	self.fallback_stt = clazz()

If it was changed to this:

    359  -   self.fallback_stt = clazz()
    359  +  if clazz:
    360  +      self.fallback_stt = clazz()

I think it may work
