How reproducible:
100%

Is this issue a regression from an earlier version:

Steps to Reproduce:
1. Follow documentation for Convert2RHEL and perform Convert2RHEL analyze job
2. As per prerequisites, the repo  'rhel-7-server-rpms' is already enabled.

Actual behavior:
Required repo  'rhel-7-server-rpms' already enabled on Satellite.
Convert2RHEL analyze job reports it as does not match a valid repository ID. Use "subscription-manager repos --list" to see valid repositories

Expected behavior:
As the repo is already enabled on Satellite this step should pass without issue.
