Foreman » Katello

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1268012
Description of problem:
It is impossible to delete an unused "Default Location" from Satellite 6.1 either through webUI or hammer CLI

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

How reproducible:
100%

Steps to Reproduce:
1. Install fresh Satellite 6.1 without specifying --foreman-initial-location and --foreman-initial-organization parameters, which would create a Default Organization and Default Location
2. Create a new Organization and Location of choice in Satellite webUI
3. Try to delete the old "Default Location" which fails with error "Cannot delete the default Location"

Same result from the hammer CLI as well
hammer> location list
[Foreman] Username: admin
[Foreman] Password for admin:
---|-----------------
ID | NAME
---|-----------------
2 | Default Location
4 | ACME_Corp
---|-----------------
hammer> location delete --id 2
Could not delete the location:
Cannot delete the default Location

Actual results:
Cannot delete the default location

Expected results:
Satellite should allow delete unused locations

Additional info:

1. foreman-rake console
   Loading production environment (Rails 3.2.8)
   irb(main):001:0> Location.all
   2015-10-01 20:15:03 [D] Location Load (0.7ms) SELECT "taxonomies".* FROM "taxonomies" WHERE "taxonomies"."type" IN ('Location') ORDER BY title
   => [#<Location id: 2, name: "Default Location", type: "Location", created_at: "2015-08-31 15:13:09", updated_at: "2015-08-31 15:13:09", ignore_types: ["ConfigTemplate", "Hostgroup"], description: nil, label: nil, apply_info_task_id: nil, ancestry: nil, title: "Default Location", katello_default: true>, #<Location id: 4, name: "ACME_Corp", type: "Location", created_at: "2015-09-02 12:13:08", updated_at: "2015-09-21 16:25:28", ignore_types: ["ConfigTemplate", "Hostgroup"], description: "", label: nil, apply_info_task_id: nil, ancestry: nil, title: "ACME_Corp", katello_default: false>]

As from the above rake output if the "katello_default: true" parameter is set for the location, Satellite 6 would not allow to delete it.
