Support for IN operator in Db Module

#### What are you trying to achieve?
I wanted to check that `$I->dontSeeInDatabase` from a list of values. Instead of writing
```php
$I->dontSeeInDatabase('someTable', ['foo' => 'cond1']);
$I->dontSeeInDatabase('someTable', ['foo' => 'cond2']);
$I->dontSeeInDatabase('someTable', ['foo' => 'cond3']);
```
I ended up writing
```php
$I->dontSeeInDatabase('someTable', [
'foo' => ['cond1', 'cond2', 'cond3']
]);
```
hoping that it would generate the following query `SELECT count(*) FROM someTable WHERE foo IN ('cond1', 'cond2', 'cond3')` and assert that the result must be 0. However I ended up getting an exception, saying array-to-string conversion - obviously enough since this is not supported.

Do you think this is something good to have, or just bad test design on my part?

Commencez au point d’entrée $I->dontSeeInDatabase du module Db et suivez la manière dont les conditions de tableau sont converties en requête. Reproduisez le cas signalé d’un tableau de valeurs, puis ajoutez la prise en charge du comportement IN demandé et vérifiez que l’assertion résultante considère les lignes correspondantes comme absentes.
