Scene Caching Tries to Access the Wrong File in Certain Circumstances

See original GitHub issue

Consider the following scene:

class Issue3DCache(ThreeDScene):
    def construct(self):
        self.begin_ambient_camera_rotation(rate=0.1)
        self.wait()
        self.wait()

when I run manim once, it makes a black screen as expected, but when I run it again, it crashes saying that it can’t find the partial movie file.

When running manim test.py Issue3DCache -pl the first time:

Animation 0 : Partial movie file written in {'.../480p15/partial_movie_files/Issue3DCache/2314591449_1-0_2415171488.mp4'}
Animation 1 : Partial movie file written in {'.../480p15/partial_movie_files/Issue3DCache/1347326907_1-0_2415171488.mp4'}

When running it again:

Wait 0 : Using cached data (hash : 2314591449_1-0_2415171488)
Animation 1 : Partial movie file written in {'.../480p15/partial_movie_files/Issue3DCache/2314591449_1-0_2415171488.mp4'}

If it worked for you, I’m fine trusting that. I don’t really know any way to test it right now short of uninstalling my copy and then installing from your fork, and that seems like more trouble than it’s worth.
