Make the Cobertura profile inactive by default

... and consider moving to Clover instead. It works well with Java 8.

Also an option would be JaCoCo ?
And yes we need to leave cobertura behind..

If this plugin is enabled, you can not run site generation under Java 12 (tested with extra-enforcer-rules)

What should we do here? Is JaCoCo they way to go nowadays?

[andham]

I've added openjdk11 to the travis ci build and it now shows this problem with cobertura by failing all opendjk 11 builds.

Fixed by #79, which removes cobertura-m-p all together.

Fixed by #7, which removes cobertura-m-p all together.

@andham, should this be #77 :-)

[andham]

@mfriedenhagen I think it should be #79, which is the fix (PR). I blame my keyboard for the typo.
I've updated the comment so that mention links are correct.
