Enterprise: Date editor shows '00000000' when data is blank

Describe the bug
When the dataGrid makes a cell editable, if there is no cellText it fetches the field value. The field value in our application has zeros for blank date values. The date editor opens with zeros.

Below is the code that is being referenced.

    makeCellEditable: function(row, cell, event) {

      if (!this.isCellEditable(row, cell)) {
        return;
      }

      //Locate the Editor
      var col = this.columnSettings(cell);
      if (!col.editor) {
        if (event.keyCode === 32) {
          this.toggleRowSelection(this.activeCell.node.closest('tr'));
        }
        return;
      }

      // Put the Cell into Focus Mode
      this.setActiveCell(row, cell);

      var cellNode = this.activeCell.node.find('.datagrid-cell-wrapper'),
        cellParent = cellNode.parent('td'),
        cellValue = (cellNode.text() ? cellNode.text() : this.fieldValue(this.settings.dataset[row], col.field));

      if (cellParent.hasClass('is-editing')) {
        //Already in edit mode
        //Editor.focus
        cellNode.find('input').focus();
        return false;
      }

To Reproduce
Steps to reproduce the behavior:

1. Edit datagrid/example-editable so that the date or orderdate is '00000000'
2. open http://localhost:4000/components/datagrid/example-editable

Expected behavior
Expect if there is no cell text then either an empty string is passed or the field value is formatted.
