Do check_repository_format() early (re-fix)
This pushes check_repository_format() (actually _gently() version) to setup_git_directory_gently() in order to prevent from using unsupported repositories. New setup_git_directory_gently()'s behaviour is stop searching for a valid gitdir and return as if there is no gitdir if a unsupported repository is found. Warning will be thrown in these cases.
