Description

Description of problem:
If one or more hosts don't have a valid subscription then running "hammer csv content-hosts --export" to save the current assignment of subscriptions fails with error "Error: undefined method `clear' for nil:NilClass"

Version-Release number of selected component (if applicable):
tfm-rubygem-hammer_cli_import-0.11.2

Steps to Reproduce:
1. Ensure that at least one content host does not have a valid subscription
2. Run "hammer csv content-hosts --export --file content-hosts-export.csv --itemized-subscriptions"

This issue can not be reproduced by removing a subscription from an already entitled host.
This issue can be reproduced by creating a new host ("Hosts" --> "New host") so the host entry is created but the host hasn't registered yet (e.g. it's still being provisioned).


Actual results:
Error: undefined method `clear' for nil:NilClass

File content-hosts-export.csv only contains the first header line.

Expected results:
Hosts without subscriptions are skipped and output file is successfully created with correct subscription assignments for hosts with valid subscriptions.
