Force update of the thumbnail preview in datatable
Force update of the thumbnail preview in datatable

The show() method was always returning the same
HTML string, so the thumbnail was requested at the
first call, and was never requested after (even
after updating the thumbnail).

Adding the timestamp to the image source forces
the browser to request the thumbnail when the
formly field is linked.
