Issue Description

Since 1.3.0 update u3d install 2019.4.35f1 fails to execute with following error trace:

I've checked unity_hub_modules folder. It contains all other version files but there is no particular 2019.4.35f1-mac-modules.json
I'm lame at Ruby so it isn't clear to me why this particular might be missing. I assume this is the unknown consequence of #416

Would appreciate any help on this. Thanks in advance!

Fix coming, sorry for that. The ruby style auto-correct code introduced a bug.
