[TIMOB-6949] Android: UI - table filter does not hide empty headers

Problem

On Android, filtering a table displays all the headers, even though some contain no rows. It should only display the headers of the matching table rows. This works correctly on iOS - see the attached screenshots which show the difference between the two platforms.

Testcase

Write "a" in the searchbar and you'll also see the "b" and "c" headers, even though they don't have any items.

Ti.UI.backgroundColor = 'white';
var win = Ti.UI.createWindow();

var table = Ti.UI.createTableView({
  search: Ti.UI.createSearchBar(),
  filterAttribute:'title',
  filterCaseInsensitive:true,
  data: [
    {
      title: 'a',
      header: 'a'
    },
    {
      title: 'b',
      header: 'b'
    },
    {
      title: 'c',
      header: 'c'
    }
  ]
});
win.add(table);
win.open();
