Correct bad merge

There was a bad merge between

• https://github.com/duritong/puppet-nftables/pull/13
• https://github.com/duritong/puppet-nftables/pull/14

correct tests.

More over I think a lot of these tests could be removed. e.g.

it {
          is_expected.to contain_concat__fragment('nftables-inet-filter-chain-INPUT-rule-drop_invalid').with(
            target:  'nftables-inet-filter-chain-INPUT',
            content: %r{^  ct state invalid drop$},
            order:   '06',
            order:   '06-nftables-inet-filter-chain-INPUT-rule-drop_invalid-b',
          )
        }

being tested in inet_filter_spec.rb is I would say redundant now that nftables::rules is well covered by its own test.

Changing it for

it { is_expected to conain_nftables__rule('INPUT-drop_invalid).with(.... ) }

is good enough and easier to maintain moving forward.
