Bug: RichSelect without options:[] property returns null on getList()

In Webix 5.1.1, a richselect created without specifying the options:[] property returns null on getList() call.

A typical pattern is to create a blank richselect and then load the items using richselect.getList().parse(newdata).

I walked around this problem by specifying an empty array (options:[]) during creation.

It is an expected behavior - the control will not create a popup if no data is provided for it.

The empty array does this task, it creates a suggest with blank data, which is already usable: https://snippet.webix.com/zs4j66o6
