title: mutli_select - select2 - repopulate field values
body: <p>I am using datatables 1.10.x, yadcf 0.9.2(beta), select2 4.0.1.</p>
  
  <p>I have this weird problem, that all of my default multi_select fields (select2) aren't repopulated after a page refresh by default. (stateSave)</p>
  
  <p>When I try to recreate it on JSFiddle it works absolutely perfect. 
  When I use costum data to match my mData changes it works superb aswell.</p>
  
  <p>Only the default one without any changes at all does not repopulate the field value. The filter is set and does work:</p>
  
  <p><strong>Before refresh:</strong></p>

  <p><strong>After refresh:</strong></p>
