This should not happen. Setting root override to a non-valid Engine directory should fail.
Currently it always saves the override no matter what, and only prints warning.
In https://github.com/adamrehn/ue4cli/pull/65 I already changed warning to error by throwing UnrealManagerException.
Now I need to also prevent the override from being saved.
This is a bit tricky to fix as currently we save the override first and then validate it afterwards:
