The bug

When deploying from a trigger, Octopus is unable to use dynamic packages (feed selection) via variables within a library variable set

What I expected to happen

Since this works with Project level variables, I'd expect this to work the same way

Steps to reproduce

1. Create a project with a Deploy a Package step
2. Set the package to a variable from a Library Variable Set
3. Create a deployment trigger with "Deploy new release" selected
