Fix a bug that Voice IME is not triggered properly.

Background:
Both SubtypeSwitcher and VoiceConnector have an instance of VoiceInput.
And VoiceConnector has a responsivity for setting VoiceInput to SubtypeSwitcher.
But in case that VoiceInputConnector already has an instance of VoiceInput
VoiceInputConnector doesn't set VoiceInput to SubtypeSwitcher.
