Writing an empty list to a cell results in an error

[sentientmachin3]

To reproduce this bug you just need to try to write an empty list to a cell.
This results in an error Cannot read property 'length' of undefined.

I think I already have spotted out the problem, here:

.case("array", values => {
                const numRows = values.length;
                const numCols = values[0].length; <---
                const range = this.rangeTo(this.relativeCell(numRows - 1, numCols - 1));
                return range.value(values);
            })

If the list is empty, the values[0] is undefined, which means it is impossible to read the property length.
