Creating object pools leaves behind remote configuration in pool repository

To create object pools we use git-clone(1), which leaves behind the configuration of the repository we cloned from. This is not information we cant to have in our repositories given that it would eventually be cleaned up anyway via housekeeping.CleanStaleData(). We should improve the code to remove the remote before returning.
