In Foreman 1.4.1 I am unable to clone an existing VMware vm via foreman.

I think the issue is around having the 'use_shortname_for_vms' option set and the change made in http://projects.theforeman.org/issues/4234 (this diff http://projects.theforeman.org/projects/foreman/repository/revisions/130f301a508ae31549145e5fa9b176f42dc20995/diff/app/models/host/managed.rb)

the fix is to alter line 159:

- name.include?('.') ? name : "#{name}.#{domain}"
+ (name || '').include?('.') ? name : "#{name}.#{domain}"

STR:
1. create a new vmware vm with the 'use_shortname_for_vms' foreman option turned on
2. attempt to clone it
3. clone fails with error: undefined method `include?' for nil:NilClass

trace from production.log:

Operation FAILED: undefined method `include?' for nil:NilClass
