IMPALA-10140: Fix CatalogExeception for creating database with sync_ddl as true

IMPALA-7961 handle the cases for query "create table if not exists"
with sync_ddl as true. Customers reported similar issue which happened
for query "create database if not exists" with sync_ddl as true.
This patch adds the similar fixing as the fixing for IMPALA-7961 to
function CatalogOpExecutor.createDatabase() to fix the issue.

Testing:
 - Manual tests
   Since this is a racy bug, I could only reproduce it by forcing
   frequent topicUpdateLog GCs along with a specific sequence of
   actions, like: run some DDLs and REFRESHs to trigger a GC in
   topicUpdateLog, then run query "create database if not exists" with
   sync_ddl as true. Verified that the issue couldn't be reproduced
   after applying this patch.
 - Passed exhaustive test.
