revert useless tests fixtures changes

This will revert #25847. Basically, the changes done in #25847 were not wrong per se. However, those changes were not necessary as the tests were not failing because of the missing "assets" config, but due to an issue introduced in the Config component. Furthermore, removing this part of the config fixtures gives us the benefit that our before normalization logic that enables assets support when the templating integration is enabled is properly tested.
