Is it possible to use this without using the dump functionality?

Dear,

We would like to use the action functionality (dontSeeInCollection, ...) but we are not using the dump functionality.
When we run the tests, we get an error.

`In MongoDb.php line 120:
[Codeception\Exception\ModuleConfigException]
MongoDb module is not configured!
File with dump doesn't exist.
Please, check path for dump file: tests/_data/dump`

At the moment dump_type is required. Would it be possible to make this optional or maybe create a MongoDb::DUMP_TYPE_NONE?

We would also do the clean up after the tests by our selfs.
