### Godot version

4.0.beta16

### System information

windows 10

### Issue description

whenever an animation starts playing and there is an animation track in it with at least one key, the seemingly innocuous error message gets printed:
```
ERROR: Condition "!playback.current.from" is true.
   at: seek (scene/animation/animation_player.cpp:1784)
```
It apparently doesn't cause any kind of erroneous behavior, and the other animation player seems to play the animation as expected.

### Steps to reproduce

### Work Around

Instead of using animation playback tracks, the user can use method call tracks and call the play method in the desired animation player
StringName name = p_name;
	if (String(name) == "") {
		name = playback.assigned;
	}
	ERR_FAIL_COND_MSG(!animation_set.has(name), vformat("Animation not found: %s.", name));
	Playback &c = playback;
	if (c.current.from) {
		double blend_time = 0.0;
		
		BlendKey bk;
		bk.from = c.current.from->name;
		bk.to = name;
		if (p_custom_blend >= 0) {
			blend_time = p_custom_blend;
		} else if (blend_times.has(bk)) {
			blend_time = blend_times[bk];
		} else {
			bk.from = "*";
			if (blend_times.has(bk)) {
				blend_time = blend_times[bk];
			} else {
				bk.from = c.current.from->name;
				bk.to = "*";
				if (blend_times.has(bk)) {
					blend_time = blend_times[bk];
				}
			}
		}
		if (p_custom_blend < 0 && blend_time == 0 && default_blend_time) {
			blend_time = default_blend_time;
