Bug #29571: INSERT DELAYED IGNORE written to binary log on

Browse Source 
the master but on the slave

MySQL can decide to "downgrade" a INSERT DELAYED statement
to normal insert in certain situations.
One such situation is when the slave is replaying a 
replication feed.
However INSERT DELAYED is logged even if there're no updates
whereas the NORMAL INSERT is not logged in such cases.

Fixed by always logging a "downgraded" INSERT DELAYED: even 
if there were no updates.
