[CAN-13042] Multi out instrument tracks still broken after disabling PLEASE RESPOND STEINBERG

I don’t usually use Import Track From Project, but had cause to do so just now. Even that doesn’t work - it imported the 2 audio tracks I needed but broke an instance of Battery 4 in the project, citing missing inputs when I imported those audio tracks. Identical behaviour on two attempts.

The entire import engine is stuffed really, whatever is mucking things up I think is code that is shared among many different functions. I hate to make one of those “grass is always greener” posts, but Pro Tools’ session import is rock solid, as are Track Presets.
