Regression in 1.15.x: Detached ruleset is not allowed outside of variable declaration

[gsmet]

Hi,

We found a regression introduced between 1.14.0 and 1.15.0.

The following snippet was parsed OK in 1.14.0 and throws an exception starting from 1.15.0 (and it's still present in master):

.print() {
  a:not(.btn) {
    text-decoration: none;
  }

  .make-grid(sm);
}

The exception thrown is the following:

org.junit.ComparisonFailure: src/test/resources/compile-basic-features/not/not.less expected:<[]> but was:<[Errors produced by compilation of testCase
ERROR 2:15 Detached ruleset is not allowed outside of variable declaration.
 1: .print() {
 2:   a:not(.btn) {
 3:     text-decoration: none;]>
    at org.junit.Assert.assertEquals(Assert.java:115)

    at com.github.sommeri.less4j.AbstractFileBasedTest.compileAndCompare(AbstractFileBasedTest.java:64)

If we remove the :not(.btn), it works ok so it seems to be related to the presence of the :not().
