Description of problem:

If an activation key is to install files and deploy files from a configuration channel. It won't deploy files front conf channels if all the packages to install were already installed. If it had to install just one package, config channels will deploy normally. 

Version-Release number of selected component (if applicable):
rhn-setup-1.0.0.1-4.el6.noarch

How reproducible:
Always

Steps to Reproduce:
1. Create an activation key
2. Add packages to install already installed and updated on the test system
3. Add a config channel with some files to deploy.

Actual results:

rhnreg_ks will show something like (these were my files which I had put also on the kickstart profile on an overzealous action).
Package rhncfg-5.10.55-6.el6sat.noarch already installed and latest version
Package rhncfg-actions-5.10.55-6.el6sat.noarch already installed and latest version
Package rhncfg-client-5.10.55-6.el6sat.noarch already installed and latest version

Files from config channel won't show after registration.

On the Failed actions on Satellite Server it will show
For: Schedule a config deploy for activation key scheduled by (none)
This action's status is: Failed.
This action has not yet been picked up. 
This action requires the successful completion of a prior action before it can be rescheduled.

For the prerequisite (Package Install scheduled by (none))
Client execution returned "Error while executing packages action: empty transaction [[6]]" (code -1)
Packages Scheduled:

    rhncfg
    rhncfg-actions
    rhncfg-client

Expected results: Ignore the empty transaction error as it is ok and deploy files.
