Authentication failure on MongoDB

#### What are you trying to achieve?
I'm trying to use the MongoDB driver module in my tests (using an authentication database locally), but the following exception is generated:

MongoDb: Failed to list collections of the DB: auth failed

#### What do you get instead?

> Provide console output if related. Use `-vvv` mode for more details.

```bash
[Codeception\Exception\ModuleException]
MongoDb: Failed to list collections of the DB: auth failed

### Details

* Codeception version: 2.2.10
* PHP Version: 7.0.17
* Operating System: Ubuntu 16.04.2 LTS (vagrant box)
* Installation type: Composer
* Suite configuration:

```yml
class_name: UnitTester
modules:
enabled: [Asserts, \Helper\Unit, Laravel5, MongoDb]
config:
Laravel5:
environment_file: .env.testing
```

I could fix this issue, by adding an option `'database' => 'admin'` to https://github.com/Codeception/Codeception/blob/2.2/src/Codeception/Lib/Driver/MongoDb.php#L114 `$options` array.
Problem is, that the module won't take into account any additional options, such as authenticationDatabase.

This also affects the mongorestore functionality, which doesn't have support for the `--authenticationDatabase ` option.

Start with Codeception/Lib/Driver/MongoDb.php around the options array near line 114 and the MongoDb module cleanup path reported at line 206. Reproduce the authenticated local setup, then verify that authenticationDatabase and related options are honored by both normal collection cleanup and mongorestore.
