Minor fix for automatically added option underlying

[Martin-Molinero]

Description

• Lean engine will automatically add an options underlying if not present, but in most cases the option chain will select the underlying too, so let's make sure the configurations match. Previous to this change 'fill forward' setting could be different causing the underlying to be duplicated in the data stack
