Fix some wrong quoting.t tests

I'm not sure when those zen slices were ever supposed to be magically
removed by quoting constructs that don't otherwise recognize those kinds
of variables. And I can only hope that the qww test was supposed to be
qqww, since nothing about ww implies variable interpolation.

With this, quoting.t is no longer fudged for rakudo :) .
