The m_profilerTimeline's AsyncData doesn't show in GUI when FrameData is empty

Line 325 in 7c7998c

if(!m_frameNodes[i].child.empty() || m_singleNodes[i].child.empty())

I believe this condition should be updated to

if(!m_frameNodes[i].child.empty() || !m_singleNodes[i].child.empty())

This ensures the async timeline is displayed if valid data exists in either AsyncData or FrameData.
