Parametrized build doesn't set environment variables in Mutli-configuration projects

Steps to reproduce:

1. Create a new Multi-configuration project
2. Enable "This project is parameterized"
3. Add parameters (I tried choices, strings, boolean)
4. Add "Execute shell" build step with `env` command
5. Save and "Build with Parameters"

The `env` output will not contain any parameters set on step (3), while it should and it used to work fine on Jenkins 1.x.
