Improved the Cobertura coverage report

[jhoffland]

The format of the Cobertura report did not match the Cobertura document definition. For example in some cases, the required attribute name of package and the required attribute signature of method was empty.
Resulting in tools like Jenkins not being able to interpret the report.
