New feature .animate does not work when including multiple animations to run at once #1129

Description of bug / unexpected behavior

In the past when we wanted to play multiple actions over a MObject we could include all of them in the following way: This example is working with old version and a Tex Object:

class ChangePosColScale(Scene):
    def construct(self):
        text = Tex("Text")
        text.scale(2)
        text.move_to(LEFT*2)
        self.play(Write(text))
        self.wait()

         self.play(
                 text.move_to, RIGHT*2,
                 text.scale, 2,
                 text.set_color, RED,
                 run_time=2,
             )

        self.wait()

Since this pull request 881, this code is no longer supported and the way it should be done is:

class ChangePosColScale(Scene):
    def construct(self):
        text = Tex("Text")
        text.scale(2)
        text.move_to(LEFT*2)
        self.play(Write(text))
        self.wait()

         self.play(
                 text.animate.move_to(RIGHT*2),
                 text.animate.scale(2),
                 text.animate.set_color(RED),
                 run_time=2,
             )

        self.wait()

And this code will only generate the last animation (changing color to RED) included in self.play.

Expected behavior

The expected behavior of the last code snippet is to generate an animation where the text is moved to the right, scaled to 2 and the color changes to RED.

The unexpected behavior is that it only plays the last animation included, the text only changes the color without scaling nor movement.

How to reproduce the issue

Code for reproducing the problem ```py class ChangePosColScale(Scene): def construct(self): text = Tex("Text") text.scale(2) text.move_to(LEFT*2) self.play(Write(text)) self.wait() self.play( text.animate.move_to(RIGHT*2), text.animate.scale(2), text.animate.set_color(RED), run_time=2, ) self.wait() ```

I'm using the docker image provided in the docker repo of manim community. Thanks to the team for all this amazing work.

Use text.animate.move_to(RIGHT*2).scale(2).set_color(RED). run_time and other parameters will be added when #1118 is merged.

Thanks, that worked!
