Off Mesh Links get leaked into scene view when editing a prefab with Off Mesh Link component

AI Navigation


How to reproduce:
1. Open the attached "case_1120451-OffmeshlinkBug" project
2. Open the Navigation Window and notice that the NavMesh consists of 2 planes
3. Open the Cube prefab, and then return back to the scene
4. Inspect the NavMesh by opening the Navigation window

Expected results: The NavMesh still consists of only 2 planes
Actual results: The Off Mesh Link from the prefab is now also in the scene

Reproducible with: 2018.3.3f1, 2019.1.0b1, 2019.2.0a3

Note: The leaked Off Mesh Link is used by NavMeshAgents.
