Fix BP_FunctionalTest_SimpleAvoidanceWithObstacles

[Kalchev89]

The avoidance system we use has a limitation where it doesn't handle the scenario in BP_FunctionalTest_SimpleAvoidanceWithObstacles correctly. @Leroy231 made a fix recently which will detect this case and cause soldiers to stop moving when the get blocked by another soldier to prevent them from trying to go through another soldier. In the future we can explore a solution to this but for now we should:

• [ ] Update BP_FunctionalTest_SimpleAvoidanceWithObstacles to confirm that soldiers start moving, and then they all stop because they get stuck
• [ ] remove the test from DisabledTests.json

Actually in that issue I kept the test disabled, so reopening this.
