/* "This should never happen"
Stripable's job is to save/recall the PresentationInfo flags for bus/track audio/midi VCA etc.
But I found a case where no "type" flag is set, so the strip never shows up on any UI.
Since I don't know the source of the error, I have to assume that it could happen again.
So: if a stripable doesn't have any flags set, populate them from our audio/midi track/bus identity.
