Subject: [PATCH] Fix deleting SpeechWaveGenerator

Similarly to dab5457620af "Fix deleting FrameManagerImpl*", we need a
virtual destructor. clang was complaining about it:

src/speechPlayer/src/speechPlayer.cpp:52:2: warning: delete called on 'SpeechWaveGenerator' that is abstract but has non-virtual destructor [-Wdelete-abstract-non-virtual-dtor]
        delete playerHandleInfo->waveGenerator;
        ^
