Description of problem:
on .../xmlrpc page is written that default is 1, but when creating new test plans thru xmlrpc, all of them are disabled.
Even though xmlrpc reports it as 'False' and not as '0'
The default should be True of 1.

Version-Release number of selected component (if applicable):
Nitrate 3.5.0-4

Steps to Reproduce:
1. Create new testplan thru xmlrpc
values = {'default_product_version': '219',
 'name': 'Plan3',
 'product': '149',
 'text': 'Some document to new plan',
 'type': 3}
TestPlan.create(values)
  
Actual results:
 'is_active': 'False',

Expected results:
 'is_active': 'True',
