title: UI-Grid custom filter restore listTerm
body: <p>When using UI-grid custom filters, the filters are stored in a listTerm object and in the default term object (Separated by commas).</p>
  
  <p>The default grid restore tries to restore the term object which breaks the filter.
   If I log the state in the console I can see a filters array for each column containing 2 objects a "listTerm" array containing the selected terms and a term object containing the same values separated by commas as
   term :"filvalue1, filvalue2,"
  I am sure the grid is restoring this comma separated object and treating it as a single filter text.
  any ideas how to get it recognize the comma as a separator or to do this in a different way? </p>
