MDEV-13711 Assertion failure on CREATE TABLE .. LIKE <sequence>

Browse Source 
Fixes two issues:
- Update assert in open_and_process_tables to handle sequences
- Removed not needed and conflicting mdl_context.release_transactional_locks
  in sql_sequence.cc. The MDL lock is released at end of
  mysql_execute_command().
