MoveToActor doesn't update AI's path on goal actor's move

A number of issues with MoveToActor have been observed in 4.7.2, including:
1. Not updating path on goal actor's move
2. hitting obstacles after path updating

1. Get the repro project from [Link Removed]
2. Open the project on the default map go "Simulate"
3. Observe AI running into wall once the target teleports.

4.7.1 MoveToActor() is broken (c++)
