share: reload repo after adjusting it in postshare()

When sharing a repo that's using remotefilelog, the update that happens
at the end of the `hg share` call does not see the remote repo path
that's copied in hg.postshare(). This patch reloads the repo after
hg.postshare() to address that.

This changes a subrepo test case. Note that `hg share -U; hg co tip`
worked there before, so I don't see see why `hg share` should fail. I
also don't know what a "locally referenced subrepo". So maybe this is
fixing a bug? Hopefully it's not breaking something someone actually
cares about at least. Maybe someone who knows and cares about subrepos
can review this.
