Wipe cache if there is no response from feed
Create config if it does not exists

The codepath that is executed when executing ownCloud via CLI is different than via browser. Specifically, the config is created by the user session already in `OC_Util::getInstanceId()` by a call to `setValue`. That said, this seems to be quite a bad side-effect, but for the sake of "not breaking whatever might break if we touch this" let's keep it that way for now.

When executing the autoconfig via `php -f index.php` the said session was not setup and thus no `config/config.php` file was created resulting in an installation error.

To reproduce this try to setup ownCloud via `php -f index.php` with and without that patch. (ensure to delete all existing configs before and don't access ownCloud with a browser in the meantime)
