When initializing a workspace that shares its working copy with a Git repo (i.e. `jj init --git-repo=.`), we import refs and HEAD when creating the `WorkspaceCommandHelper` (as we do for all commands when the working copy is shared). That makes the explicit import we do in `cmd_init()` unnecessary. It also makes the checkout of HEAD I added for the fix of #102 unnecessary. More importantly, as @yuja reported in #177, it makes the command crash (at least if the repo is small enough that the two checkouts happen within a second). I think the problem is that the second checkout tries to create the same commit except that the Change ID is different (the problem is not the predecessors as I speculated in the issue tracker). The fix is to simply avoid doing the redundant work. We still need a proper fix for #27 eventually. Closes #177.
