Remove dough component specific styling
Remove dough component specific styling

The popup tooltip content was being partially obscured by
some of the callout messages and was fixed by adding a z-index styling.
The fix should have been made on dough rather than on wpcc. The poptip
dough component has now been amended so we don't need this extra style.
Refer to [pr 329 on dough](https://github.com/moneyadviceservice/dough/pull/329).
