Fix resolve intrinsic function use in first parameter (#336)

**Why?**

A bug prevented the use of the `resolve:` intrinsic
function on the first parameter in in the first parameter file.

**What?**

The parameters were initialized as an empty dictionary.
While reading a file that does not exist would return a predefined
object instead. The fix uses the later instead of an empty dictionary.
