scss/comment-no-empty false positive on paragraph breaks in multi-line double-slash comments

[dbjorge]

Comments like this:

// First paragraph of a long comment
//
// Second paragraph
.some-rule { /* ... */ }

...trigger a false positive from scss/comment-no-empty on the blank line within the comment acting as a paragraph break. Here is an example accept test case that can be added to /src/rules/comment-no-empty/__tests__/index.js which demonstrates the issue:

    {
      code: "// comment\n//\n// comment",
      description: "Multiline double slash comment with paragraph break"
    },

  ● scss/comment-no-empty › accept › [ true ] › '// comment\n//\n// comment' › Multiline double slash comment with paragraph break

    expect(received).toEqual(expected) // deep equality

    - Expected  - 1
    + Received  + 9

    - Array []
    + Array [
    +   Object {
    +     "column": 1,
    +     "line": 2,
    +     "rule": "scss/comment-no-empty",
    +     "severity": "error",
    +     "text": "Unexpected empty comment (scss/comment-no-empty)",
    +   },
    + ]
