Internal issue 2759 - ic-data-table#createCells() throws on null data value

[ticket-sync[bot]]

The createCells() function of the ic-data-table component throws an error when null is passed as a cell value through the table’s data prop. This is due to an incomplete type check when calculating the hasIcon variable (it uses this.isObject() which only checks for a typeof value of “object”, which is also produced by null). When the subsequent code then tries to run Object.keys() on null, the function throws a TypeError and the whole table fails to render.

Consider what a null value looks like in a cell - do we still throw a warning? Write tests.
