Disconnect signals before releasing reference to objects
Crash bug occurs when QWaveDecoder reads the whole file in one go
and emits formatKnown() signal followed by readyRead() signal.
The formatKnown() signal handler clears the m_waveDecoder pointer,
which the subsequence readyReady() handler tries to dereference.
This patch disconnects all signals before clearing m_waveDecoder
avoiding this problem.
Fixes: QTBUG-96642
