Fix bogus handling of error replies.

Error replies returned by Redis were erroneusly triggering the automatic
reconnection of the client thus leading to infinite loops.

An automatic reconnection mechanism probably sounds nice at first but can
easily lead to unexpected behaviours, and considered that we don't support
them in the binary-safe variants of the commands function it's better to
drop this feature altogether.

This commit fixes issue #12.
