Fixed an unexpected exception bug when reconnecting in pub/sub mode if selected_db is not null

Browse Source 
RedisClient might enter pub/sub mode after at least one SELECT command issued.
When reconnecting, the SELECT command is issued after restoring pub_sub_command to true, which causes an exception.
