In cases where the HEAD branch of a repository is deleted, prepare-workspace-git will be unable to propagate that deletion from the executor repos to a clone of a cached repo on a remote node. Correct this by unsetting the receive.delyDeleteCurrent flag. This was correctly set in mirror-workspace-git, but did not make it into prepare-workspace-git.
