Fix MIDI deinterlace #9422

Browse Source 
De-interlace works by first creating 16 SMF Sources, and then
only using sources that are actually required.

However SourceFactory::createWritable by default emits SourceCreated,
which added all the 16 Sources to the Session. Later adding only the
required Sources resulted in duplicate IDs.
