Description of problem:


Hammer csv content-view-filters cannot properly handle CV Filters that use date-based Erratum. The export has the following output :

Name,Content View,Organization,Type,Description,Repositories,Rules
Errata until 2017-01-01,CV_RHEL72,MyOrg,Include unknown,,"","start = 2000-12-31,end = 2016-12-31,""types = security,enhancement,bugfix"""

The "Include unknown" field is wrong, and makes the import process fail:

Error: 500 Internal Server Error
Errata until 2017-01-01,CV_RHEL72,MyOrg,Include unknown,,"","start = 2000-12-31,end = 2016-12-31,""types = security,enhancement,bugfix"""
