config: expanded pitest mutators to defaults

[rnveach]

This is in support of #6264 .

Defaults are not added by default when you start adding new mutators. Just adding the new one without the defaults results in only the new mutator running. This is what I used to generate the report in the first post of the issue.

Please confirm, that no new mutations were added and all referenced are defaults, is there a link to that list at pitest web site ?

that no new mutations were added

Isn't this what what our pitest.sh script does in circleCI?
CI passed so percentages remained the same, and script didn't find any new survived mutations. Only package we don't really test is gui.

You can see old pitest report at http://rveach.no-ip.org/checkstyle/regression/pitest-reports/18/ (commit is in the report ).

all referenced are defaults, is there a link to that list at pitest web site ?

I forgot to include the link.
I am using this list as the list of defaults: https://github.com/hcoles/pitest/blob/6101377de641c57a17ff82545682b9b7fbc3c061/pitest/src/main/java/org/pitest/mutationtest/engine/gregor/config/Mutator.java#L209-L215

You can also see defaults in their document at http://pitest.org/quickstart/mutators/ . See activated by default on top.
