Change the default settings on the exhibition races to freeroam

It never made sense to me that the races default settings were all presets. The game would be so much more dynamic if the default settings for every race were Freeroam/Freeroam, with the exception of street races, which should still have Freeroam for weather but a preset time of day.

Setting up eventlab blueprints for each race I want to do takes too much time for the time spent racing, and it takes up a valuable custom race spot (we only get 5 per start point).

This is a small, but quick and easy fix to make casually cruising around the map doing quick single player races a far more enjoyable and dynamic experience.
