Description of problem:
Hi,

The supertuxkart with update-testing is crashing. The reason is, when I have done update --enablerepo=updates-testing, it is not updated. So, it crashed as soon as I start it.

For check, I removed it and made a clean install, now angelscript's updated version(2.30.2-2) is downloaded, and running smoothly.

I think this should be inbuilt, and angelscript should be automatically updated when supertuxkart is updated. 

As proof:
1) Supertuxkart update 
sudo dnf update --enablerepo=updates-testing supertuxkart
