jqxKanban: cannot updateItem without tags

[SvetoslavjQWidgets]

Describe the bug The user wants to update a kanban item, but in the kanban, the 'tags' are not used, so in the updateItem he is passing tags: null. This throws an error because of the following line in updateItem function:

var o = h.tags.replace(/,\s/g, ",").split(","); (Note that this is minified and the name of the variables are different in the source)
