Fix upgrade install fails after partial install

What this PR does / why we need it:

After my initial install failed when installing rook I tried to re-run the installer. In between running the installer a second time a new k8s version was released. When i ran a second time my installer tried to upgrade k8s and failed with the following error since the kurl-config had not yet been written.
