fix addons/mysqladmin_shell.sh in 123.09beta01

Fix bug when using multidb mode in addons/mysqladmin_shell.sh if you list in dblist.txt different db username but same db username password for multiple entries, it would skip creating the db username https://community.centminmod.com/threads/mysqladmin_shell-sh-issue.14321/#post-61389.
