no-unused-variables autofix leaves empty lines

Bug Report

• TSLint version: master
• TypeScript version: latest
• Running TSLint via: CLI

TypeScript code being linted

Issue is noticeable in rule tests. Code to fix:

// This import statement is unused and will be deleted along with this comment.
import {a5, a6} from "a";
import {a7} from "a";
import {a8, a9, a10} from "a";

Which results on this fix:

// This import statement is unused and will be deleted along with this comment.


import {a8} from "a";

Actual behavior

When autofix deletes the whole import sentence, it leaves an empty line.

Expected behavior

Remove the line break when the whole sentence is deleted, so expected fix should be:

// This import statement is unused and will be deleted along with this comment.
import {a8} from "a";
