docs_as_code testlinker ignore extra properties

[PiotrKorkus]

Gtest adds extra properties to xml. Sometimes not all properties are filled. Ignore a need when not all needed propertties are filled and ignore extra properties that we don't use in codelinker. Dont raise errors in that case

[MaximilianSoerenPollak]

Additional requirement.

Testlinker should allow for properties to not all be present and just skip the test instead of it erroring.
