Improve TemplateMatching for SystemTests

[hamidonos]

Situation

Inside the TestTemplateSupport there is a method

        public boolean isMatching() {
            return transformedTemplate.equals(transformedContent);
        }

which is used to assert SecHub reports. This will only work if both strings are exactly the same.

Wanted

A more sophisticated solution which does not depend on the equality of two strings.

Solution

Make the comparison more sophisticated by parsing both strings into the object using object mapper.
Call the equals method on the objects to compare the result.
(Make sure equals is up-to-date)
