[AI] Area Class to Replace does not work on SplineNavModifierComponent

[AI] Area Class to Replace does not work on SplineNavModifierComponent

Description

The SplineNavModifierComponent does not have the same behavior as regular nav modifier components where the modifier can specify that it only replaces a given NavArea class. Setting the area class to replace is completely ignored as the modifier is applied over all navmesh affected.

Steps to Reproduce
  1. Create an Actor BP with a SplineComponent and SplineNavModifierComponent
  2. Place and edit the splines to overlap with the following settings.
  • Actor1 with AreaClass set to NavArea_Obstacle and AreaClassToReplace set to None
  • Actor2 with AreaClass set to NavArea_Null and AreaClassToReplace set to NavArea_Obstacle
