always_redraw works in 0.18.0 but not in 0.18.1 (single ValueTracker)

Nobody has claimed this yet.

## Description of bug / unexpected behavior
The following code which does not work in 0.18.1 and is fine on 0.17.3:

```python
for i, idx_r in enumerate(r_idxs):

r = points[idx_r]

if i == 0:
track_pt = PointValueTracker(r)

# lines denoting the prq angle
pr = always_redraw(lambda: Line(p, track_pt.get_value(), color=YELLOW, buff=0))
qr = always_redraw(lambda: Line(q, track_pt.get_value(), color=YELLOW, buff=0))
grp = VGroup(pr, qr)

self.play(LaggedStartMap(Create, grp, runtime=2, lag_ratio=0.2))

# move the point of two "angle" lines along the line
# connecting points[idx_r] and points[idx_r + 1]
if i < len(r_idxs) - 1:
r_next = points[r_idxs[i + 1]]
self.play(track_pt.animate.set_value(r_next))
```

Start by running the provided animation pattern with always_redraw, PointValueTracker, and the animated set_value call, comparing behavior in 0.18.0 and 0.18.1. Done means the 0.18.1 animation matches the working behavior shown in correct.mp4 rather than the failure in wrong.mp4.
