Asserts that two values are not equal by invoking {@link Comparable#compareTo(Object)}.

@param description the description of the <em>actual</em> value.
@param actual the <em>actual</em> value.
@param other the value to compare the <em>actual</em> value to.
@throws AssertionError if the <em>actual</em> value is {@code null}.
@throws AssertionError if the <em>actual</em> value is equal to the other one.
