Set up config files as soon as possible such that 'got fetch' has enough information in order to resume an interrupted clone operation. We need to receive at least a default HEAD branch name from the server before we can set up our configuration files. The previous code also verified whether the default branch name supplied by the server resolved to a commit received in the pack file. This check cannot be done early but a wrong branch name in a config file can be fixed easily.
