Criteria filter crashes after applying checkbox filter.

[Christopher]

If you attempt to choose a criteria filter after applying a "checkbox" filter, the filter will error out with:

Uncaught TypeError: Cannot read property 'criteria' of undefined<br> at eval (eval at setter (https://kendo.cdn.telerik.com/2017.2.621/js/kendo.all.min.js:25:31060), <anonymous>:3:15)

 

This appears to be a bug in the spreadsheet as it appears in our application as well as the Kendo UI demo.

 

Steps to reproduce:

1) Go to the filtering demo: http://demos.telerik.com/kendo-ui/spreadsheet/sorting-filtering

2) Click the filter on the "Client" column.

3) Uncheck a few of the client values then hit apply.

4) Click the filter again, but this time expand the filter by criteria.

5) Select an item from the dropdown.

6) Notice a javascript error occurs, and the filter cannot be applied.

Looking into this it appears that the spreadsheet/filtermenu's "operatorChange" event handler is not handling a situation where the customFilter property hasn't been set yet. 

The fix appears to be to check for it's presence, and if not found, create the default values via the reset() method and then the operator can be set properly.

I've created the bug & fix report on Github here.
