commit a43f7d5a6130550619afad3fb513c98e00dc505e

 Bug#22130929 GTID_NEXT AND BEGIN BEHAVIOR IS DIFFERENT B/W BINLOG AND BINLOG-LESS SERVER
 Problem
 =======
 When binlog is enabled, we do not save the gtid specified by
 GTID_NEXT into GLOBAL@gtid_executed when committing an empty
 transaction caused by a  BEGIN  command. But we save the gtid
 into GLOBAL@gtid_executed in the case when binlog is disabled.
 Fix
 ===
 When @@SESSION.GTID_NEXT ==  UUID:NUMBER , the command  BEGIN  causes
 an error  ER_CANT_DO_IMPLICIT_COMMIT_IN_TRX_WHEN_GTID_NEXT_IS_SET 
 inside an empty/a non-empty transaction regardless of being binlogless
 or not, since it causes an implicit commit like other DDLs. And we do
 not save the gtid specified by GTID_NEXT into GLOBAL@gtid_executed
 in the case.
