Regression: extra commands require a valid PROJECT file again

[jmrodri]

https://github.com/kubernetes-sigs/kubebuilder/blob/master/pkg/cli/cli.go#L194 returns an error when it can not parse the config file. This means that extra commands will no longer work. This affects the operator-sdk because we have a command alpha config-3alpha-to-3 that will convert 3alpha PROJECT config to valid 3 config. But the error prevents this command from ever running.

Similarly, version also no longer works if we can't parse the PROJECT config file which is a regression.

What versions of software are you using? Specifically, the following are often useful:

• go version
• kubebuilder version (kubebuilder version) and scaffolding version (check your PROJECT file): *v3.0.0-beta.1`
• controller-runtime version (check your go.mod file)
• controller-tools version
• Kubernetes & kubectl versions (just run kubectl version against your API server)

I would not consider this a regression as the previous case was when the config file didn't exist.
