Added hasMargin-prop for MCL in users results list. (#1211)
Added hasMargin-prop for MCL in users results list. (#1211)

We made a change in the `<MultiColumnList>`-component that 
removes the horizontal margin by default, making the component 
span from edge to edge.

This works for most implementations but MCL's used in the result 
panes must have the hasMargin-prop applied to enable proper 
spacing and alignment.

This PR adds that prop for the results view.
