traceback

Description of problem:
When I try to create a EC2 guests using Sat6, I get this error in production.log and guest is not registered.


Prepare post installation script for ggg.test.example.com task failed with the following error: undefined method `subscription_manager_configuration_url' for #<Host::Managed:0x007f065c9f1d98>/opt/rh/ruby193/root/usr/share/gems/gems/activemodel-3.2.8/lib/active_model/attribute_methods.rb:407:in `method_missing'

<< the complete traceback is in the attachment >>

Version-Release number of selected component (if applicable):
Satellite-6.0.3-RHEL-6-20140528.4

How reproducible:
100%

Steps to Reproduce:
1. We have got Sat6 with EC2 compute resource.
2. We have got this line in our finish template
> <%= snippets "subscription_manager_registration" %>
3. We can try create new host, but registration fails with the traceback in log.


Snippet "subscription_manager_registration" contains this row.
> rpm -ivh <%= subscription_manager_configuration_url %>


One thing is interesting, When we open a detail of guest ("Hosts" > "All hosts" > our new guest > "Templates" > our finish template > "Review"), the expansion of the variable "subscription_manager_configuration_url" is correct
> rpm -ivh http://sat.eu-west-1.compute.internal/pub/katello-ca-consumer-latest.noarch.rpm

When We replace the variable "subscription_manager_configuration_url" with link "http://sat.eu-west-1.compute.internal/pub/katello-ca-consumer-latest.noarch.rpm" in the snippet, the registration ends fine.

Actual results:
Traceback, system is not registered.

Expected results:
System is registered.
