Bug 1204903

Description of problem:
Applying errata to a content host in a non-incremental update way via the new errata page failed

Version-Release number of selected component (if applicable):
Satellite-6.1.0-RHEL-6-20150317.0

How reproducible:
Always

Steps to Reproduce:
1. Create two content views with filters so one has errata and the other doesnt.
2. Register two content hosts to each of these content views
3. Go to Content -> Errata -> Select an errata 
4. It showed me 2 content hosts as expected
5. Now uncheck 'Only show content hosts where is currently installable in the host's Lifecycle Environment'.
6. I expected to see one content hosts and it showed up correctly
7. Now select the content host and click Next
8. Apply the errata

Actual results:
Failed with the following error in production.log
[ERROR 2015-03-23 13:30:53 pulp_rest  #13143] RestClient.delete "https://ibm-x3250m4-05.lab.eng.rdu2.redhat.com/pulp/api/v2/consumer_groups/37d95da4-ef2b-42df-be3c-70b0e0a547cc/", "Accept"=>"*/*; q=0.5, application/xml", "Accept-Encoding"=>"gzip, deflate", "Authorization"=>"OAuth oauth_consumer_key=\"katello\", oauth_nonce=\"Bcc2vJzWaNc7LThXnjRukexVEIlL7n0sh0jb7nCk\", oauth_signature=\"YDs9tmXsOyXcha4AAk50QLVC3zA%3D\", oauth_signature_method=\"HMAC-SHA1\", oauth_timestamp=\"1427131853\", oauth_version=\"1.0\"", "accept"=>"application/json", "content_type"=>"application/json", "pulp-user"=>"admin-c8719da6"

Expected results:
Errata is applied in the content host

Additional info:
When I tried to redo the same scenario - this is what happened:
1. Go to Content -> Errata -> Select an errata 
2. It showed me 2 content hosts as expected
3. Now uncheck 'Only show content hosts where is currently installable in the host's Lifecycle Environment'.
4. I expected to see one content hosts and it showed up correctly
5. Now select the content host and click Next
6. Apply the errata
7. Now it said "You must select at least one Content Host in order to apply Errata."
