MDEV-21785: sequences used as default by other table not dumped in right order by mysqldump

Browse Source 
Dump sequences first.

This atch made to keep it small and
to keep number of queries to the server the same.

Order of tables in a dump can not be changed
(except sequences first) because mysql_list_tables
uses SHOW TABLES and I used SHOW FULL TABLES.
