Fix JIRA helper tests to comply with JIRA API specification

  - Remove test_issue_from_jira_is_active_with_unknown_status_and_none_resolution
  - Remove test_issue_from_jira_is_active_without_status_category_with_none_string_resolution

  These tests checked for resolution field as string 'None', which violates JIRA API spec.
  According to JIRA API, resolution is either an object with properties (id, name, etc) or null,
  never a string value. Remaining 12 tests verify correct behavior per the API spec.
