Fixed: all exceptions thrown by parser(_parseResult method) were suspected to be from parsing process, but if error is thrown in callback then it is handled in the same way, meaning that it never bubbles up to the actual application (issue #361)
RedisClient.prototype.end function bug fixed.

An uncaught exception will be raised when the retry timer tries to
reconnect and encounter an error, for all event listeners of the stream
were removed in line 826. It should set closing varable to be true.
