child selector get duplicated parent selector when assigning the parent selector

[ekskimn]

When I do:

foo {
    a:&;
    >bar {
        b:&;
        >baz {
            c:&;
        }
    }
}

I get

foo {
  a: foo; }
  foo > bar {
    b: foo foo > bar; }
    foo foo > bar > baz {
      c: foo foo foo foo > bar > bar foo foo > bar > baz; }

The fix (by @ekskimn) is included in #1249 ...

[xzyfer]

Spec added sass/sass-spec#439

Since this is a regression I've activated the spec. This will prevent #1249 being merge without the patch applied.
