Bug Report

Description:
If a Function returns ClassA|ClassB, Rector will always use the first one, to rename the Variables.

In my example I am using:

$ffmpeg = FFMpeg::create();

$video = $ffmpeg->open(Storage::disk('media')->path($this->path));

from FFMpeg::open header: * @return Audio|Video

Rector will rename my variable $video to $audio

Reproduce
Demo does not make changes, probably because FFMpeg is not found.
I have attached my console output to the demo

Expected Behaviour

I expect Rector to allow $audio and $video as possible variable names in this case specific case.

For other similar cases, I expect Rector to allow all possible return types as variable names
