title: PhoneNumberUtils is not formatting some numbers
body: <p>I need to format the number to x xxx xxx xx-xx. Here is two examples.</p>
  
  <pre><code>PhoneNumberUtils.formatNumber("+79998887766", "RU"))
  </code></pre>
  
  <p>Result is: "+7 999 888-77-66". This is what I need.</p>
  
  <pre><code>PhoneNumberUtils.formatNumber("+71112223344", "RU"))
  </code></pre>
  
  <p>Result is: "+71112223344". The number with same length is not formatted. </p>
  
  <p>How to format the second number?</p>
