Changed relay and para's barriers to block messages that do not pay for their fees.
Some examples explicitly state they do not pay for fees, might change that in the future once we make examples more real.
Changed all tests to make them pass, ignored the lock ones until https://github.com/paritytech/polkadot/pull/7278 is solved.
