Subject: [PATCH] PianoView: send NoteOff MIDI events for all keys on focus out

Commit 491910357b54a5d17e74c70ae3bb73cd780b254f was a first try to fix
bug #3052228 but it broke InstrumentPlayHandle-driven instruments.
When losing focus now simply send NoteOff MIDI events for all keys
regardless of the state indicated by Piano::m_pressedKeys.

Closes #3052228.
