mysql_db: Improve tests (#240)

- Define variables "db_names" and "db_formats" in defaults
- Use of the "vars" option in includes instead of default parameters
  that might be overridden by a previous task
- Use of the "loop" option in includes instead of duplicating include
  tasks
- Use a nested loop on db_names and db_formats in state_dump_import test
