title: tslint one line rule misplaced 'else'
body: <p>I have such <code>config</code> in <code>tslint.json</code> for <code>one line rule</code></p>
  
  <pre><code>one-line": [true,
        "check-open-brace",
        "check-catch",
        "check-else",
        "check-whitespace"
      ],
  </code></pre>
  
  <p>When I have code lines like that:</p>
  
  <pre><code>if(SomethingTrue) { next("a"); }
  else { next("b"); }
  </code></pre>
  
  <p>I've got warning:</p>
  
  <pre><code>(one-line) file.ts[17, 9]: misplaced 'else'
  </code></pre>
  
  <p>Why that is happens? 
  Is it bad practice to have one <code>line else</code>?</p>
