setEnabled to false on collider do not disable collision in 0.18.x.

[smjnab]

Since 0.18.x using setEnabled(false) on a collider sets the collider enable value to false, but the collider remains collidable in the physics world. This was not the case in <= 0.17.x.

This happens both if creating a collider description with enabled set to false and setting a created collider to enabled false.
