BugFix: TerrainMeta now updates Terrain Material if it's missmatching Unity's deprecation made it so that our validate-and-update logic broke with 2019.2 and it's been silently skipping it. - Removed obsolete code (it always returned MaterialType.Custom) - Updated Hapis TerrainConfig to reference Terrain.v3.Hapis material (so that new logic doesn't set the wrong material on validation) Tests: Validated that all Release worlds have matching materials as in their TerrainConfig.
