[BUG] Segmentation fault error caused by Morph Stress Test

[devmessias]

Description

test_morphing https://github.com/fury-gl/fury/blob/b37669f8767d460b97e17584106ad8a6b5d26491/fury/tests/test_gltf.py#L285 causes a segmentation fault error in most of the github actions. It seems correlated with the headless mode.

What I can conclude until now it is:

• It's not caused by the window manager initialize method https://github.com/fury-gl/fury/blob/b37669f8767d460b97e17584106ad8a6b5d26491/fury/tests/test_gltf.py#L300
• Removing all the vtk actors from the Timeline object after the render method doesn't solve the problem
• The double call Render method with a timeline and a gltf object seems to be the cause of the seg fault.

I've created a simple repo with just the test_morphing to debug this issue. The following zip has all the logs of the failed actions: 12_DEBUG fail-test.txt : catchsegv python3 debug_fail.py 13_DEBUG catch.txt: python3 -X faulthandler debug_fail.py
