#981 Platform deceleration higher than accel treated as accel

[AshyRaccoon]

Construct 0.99.42

Using the platform behavior on a sprite.
If I set the sprite's floor deceleration higher than its floor acceleration, the floor deceleration value is used for acceleration as well.

For example, if I set the floor acceleration to 400, and floor deceleration to 900, it acts as though the floor acceleration is 900.
If I set the floor deceleration lower than the acceleration, then it works as expected.

In a more extreme example, I can set floor acceleration to 1, and deceleration to 2000, and it acts as though the acceleration is 2000.

The last stable version did treat it like this.
I also tried this in a brand new cap, and could reproduce it there as well.

This is also the case for air deceleration which is higher than air acceleration. It will act like the air deceleration is the air acceleration setting.
