Description of problem:
Trying to register a host(already register to another Satellite) by going to Hosts -> Register Host and check the 'force' option in 'Advanced' tab is failing as the katello-ca-consumer installed is not being removed.

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


How reproducible:
100%

Steps to Reproduce:
1. Satellite webUI -> Hosts -> Register Host
2. Fill the fields and in the 'Advanced' tab check the 'Force' options
3. Register the host with the registration command generated

Actual results:
The registration command does not remove the katello-ca-consumer packages.
The 'Force' option is supposed to:
---
 "Remove any `katello-ca-consumer` rpms before registration and run subscription-manager with `--force` argument."
--
The script seems to look for this 'katello-ca-consumer-latest.noarch.rpm' and can't find a package with this name installed.
Expected results:
Remove the katello-ca-consumer and install a new one. Otherwise, the transaction will conflict:
---
Transaction check error:
  file /usr/bin/katello-rhsm-consumer from install of katello-ca-consumer-rguerra-sat610.rguerra.lab-1.0-1.noarch conflicts with file from package katello-ca-consumer-rguerra-cap610.rguerra.lab-1.0-1.noarch

1. Register the system to a satellite server:
[root@rhel7-02 ~]# subscription-manager register --org="ACME" --activationkey="ak-rhel7-library" --force
The system has been registered with ID: 2d9c0316-717d-4422-91b0-c2761c87b84a
The registered system name is: rhel7-02.rguerra.lab

Status:       Subscribed

[root@rhel7-02 ~]# rpm -qa |grep katello-ca
katello-ca-consumer-janga.rguerra.lab-1.0-9.noarch


2. Run the script generated on another Satellite:
[root@rhel7-02 ~]# curl -sS --insecure 'https://rguerra-sat610.rguerra.lab:9090/register?activation_keys=ak-rhel7&force=true&lifecycle_environment_id=2&location_id=2&operatingsystem_id=1&organization_id=1&update_packages=false' -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjo0LCJpYXQiOjE2MjkzMDY2ODMsImp0aSI6ImFjMTdhNmNkMTI4MmFkY2RiYzExNzkxMTVlNDEyMmI3ZDI0MTNjY2VlYmU4MDM3YjFjZjBjYmNhYTFmOTM2NDQiLCJleHAiOjE2MjkzMjEwODMsInNjb3BlIjoicmVnaXN0cmF0aW9uI2dsb2JhbCByZWdpc3RyYXRpb24jaG9zdCJ9.goxamrSaQs63-Jjd4HwofckTk9eAIR2dza2YTjE3fiM' | bash
