client: ignore close() on non-open clients (issue5751)

Closing a client twice currently triggers a rather confusing exception.
Instead, follow the convention set by Python's file objects, and ignore close()
commands on non-open clients.

            list.append(args[0])
            return f(*args, **kwargs)
        return decorated
    return decorator

        self._oldopen = hglib.client.hgclient.open
        # hglib.open = resultappender(self.clients)(hglib.open)
        c = hglib.client.hgclient
        c.open = resultappender(self.clients)(c.open)

        os.mkdir(self._testtmp)
        os.chdir(self._testtmp)
        # until we can run norepo commands in the cmdserver
        os.system('hg init')
        self.client = hglib.open()

    def tearDown(self):
        # on Windows we cannot rmtree before closing all instances
        # because of used files
        hglib.client.hgclient.open = self._oldopen

            shutil.rmtree(self._testtmp)
        except AttributeError:
            pass # if our setUp was overriden
