Fix SMT
This might be a fix for some issues in ATLASDPD-1334, I'm pretty sure the problem there was that we were asking for track decorations by the wrong names.
This fixes this by changing the default convention to something consistent with what we use everywhere else. We might want to make this more configurable at some point but it's not clear if we'll go back to the default convention that I'm moving away from now.
