Clip Count is not updated correctly when Animator.runtimeAnimatorController is changed twice on the same frame



Reproduction steps:
1. Open the user's attached "AnimatorCrash -" project
2. Load the "SampleScene"
3. Select the "Animator" GameObject in the Hierarchy window and enter Play mode
4. Open Game view and press C key on the keyboard
5. Observe the "Clip Count" value of the Animator Component in the Inspector window
6. Press the C key again

Expected result: Runtime Animator Controller is set to the "AnimatorController" and Clip Count is 1
Actual result: Runtime Animator Controller is set to the "AnimatorController" but Clip Count is 0

Reproducible with: 2019.3.12f1, 2019.3.16f1, 2019.4.0f1, 2020.1.0b12, 2020.2.0a14
Not reproducible with: 2018.4.23f1, 2019.3.11f1

Note: a warning message appears each time Clip Count is set to 0: "PlayableGraph being evaluated with no outputs. Playables will not be updated"
