Groups definition in (global) config lead to warning "Array to string conversion" in Run.php line 592.

#### What are you trying to achieve?

Use a global groups definition, as defined at [https://codeception.com/docs/Customization#Group-Files](https://codeception.com/docs/Customization#Group-Files).

This is required in order for infection/infection to work with codeception.

#### What do you get instead?

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

##### 1. Groups definition in config:

codeception.yml
```yml
groups:
infection: [path/to/SomeTest.php]
```

Run `codecept run -g infection`

##### 2. Overwrite when calling `codecept run` (this is what `infection/infection` does)

Run `codecept run -g infection -o "groups: infection: [path/to/SomeTest.php]"`
