Description of problem:
If I import a new version of a module, with a different default for one of it's parameters into a CV in a certain lifecycle environment, I would expect to be able to switch between environments on Satellite's smart parameter edit page (.../puppetclasses/157-bar/edit) and see the default change.

I only see the value of the first class that was imported though: the default never changes when selecting another environment, even though this is valuable information.

Version-Release number of selected component (if applicable):
6.2.0 SNAP 10

How reproducible:

Steps to Reproduce:
1. Upload / import a module, make sure it ends up in a published CV
2. Change a default parameter value for the module, upload / import it again and make sure it ends up in a published CV; make sure the two CVs are in different life cycle environments, so the second one doesn't overwrite the first one
3. Go to .../puppetclasses/157-bar/edit for this module

Actual results:
Switching the environment shows no change in the default value field of the parameter

Expected results:
Switching the environment shows that you changed the default value of the parameter

Additional info:
Modules that use a params.pp aren't touched by this, but there are enough modules out there that do not have all default values in a params.pp
