Removing trailing space after a command if there are no arguments.

According to the Memcached Protocol, the no argument form of the stats command should have no trailing spaces. Currently, b'stats \r\n' instead of b'stats\r\n' is being sent to the socket which leads to a malformed response.

It looks like you'll also need to update the stats tests with the new (correct) behavior:

pymemcache/test/test_client.py:925: in test_stats_conversions
    assert client.sock.send_bufs == [
E   AssertionError: assert [b'stats\r\n'] == [b'stats \r\n']
E     At index 0 diff: b'stats\r\n' != b'stats \r\n'
E     Full diff:
E     - [b'stats \r\n']
E     ?         -
E     + [b'stats\r\n']

Noted, thanks I've updated the test cases and I got the automated checks to pass.
