Missing cobertura fields

[sw-tracker]

Hi there,

When I convert a report from jacoco to cobertura, there are fields missing:

Teamop/merge-cobertura#1

Fields missing:

• lines-valid
• lines-covered
• branches-valid
• branches-covered

The issue is that after converting the report to cobertura, I merge this report with typescript cobertura reports and because these fields are missing, we end up with NaN values.
