Description of problem:
Creation of an user via API with default_organization_id set fails with 500 ISE.

Version-Release number of selected component (if applicable):
Satellite-6.0.3-RHEL-6-20140423.1-Satellite-x86_64-dvd1.iso

How reproducible:
always

Steps to Reproduce:
1. Run @api.resource(:users).call(:create, user_hash) with following user_hash:
user_hash = {
:login => "newuser",
:firstname => "user",
:lastname => "new",
:mail => "root@localhost",
:auth_source_id => 1,
:password => "password",
:organization_ids => [13],
:default_organization_id => 13,
:location_ids => [],
:role_ids => [],
}

Actual results:
Creation of user failed with: 500 Internal Server Error: {
"error": {"message":"undefined method `key?' for #<JSON::Ext::Generator::State:0x007f696cecadd8>"}
}
but the user was created!

Expected results:
no exceptions or ISEs

Additional info:
- creating of the user without default_organization_id works and setting it using the user update API afterwards works as well
