salt: pkg version: latest are now broken, appending -latest to filename

Description of Issue/Question

I’m trying to use a very simple state:

sl:
  pkg.installed:
    - version: latest

This does not work on Red Hat 6 but it works perfectly fine on Ubuntu 16.04

The minion tries to install package sl-latest instead of the latest version of sl

The same state works perfectly fine on Ubuntu 16.04 where the latest sl package was installed. Using Ubuntu it did not add -latest to the filename.

Steps to Reproduce Issue

Install Red Hat 6 Run the following state:

sl:
  pkg.installed:
    - version: latest
