This PR solves the following issues encountered using question helper and choices questions:
- First choice was not selectable by value.
- ChoiceList with associative choices with mixed string and int keys has same issue with first choice.
- Fix inconsistency by always returning values as strings.
First point exemple:
![screenshot 2015-05-15 a 17 16 12](https://cloud.githubusercontent.com/assets/2211145/7655757/3344b39a-fb26-11e4-9fe7-0775616619bf.PNG)
Last two points are mainly edge cases. Indeed, if a QuestionChoice has something like :
```php
array(
'0' => 'No environment',
'1' => 'My environment 1',
'env_2' => 'My environment 2',
3 => 'My environment 3',
);
```
as choices, you will not be able to select the first choice and get an `InvalidArgumentException`:
```
There were 2 errors:
1) Symfony\Component\Console\Tests\Helper\QuestionHelperTest::testChoiceFromChoicelistWithMixedKeys with data set #0 ('0', '0')
InvalidArgumentException: Value "0" is invalid
2) Symfony\Component\Console\Tests\Helper\QuestionHelperTest::testChoiceFromChoicelistWithMixedKeys with data set #1 ('No environment', '0')
InvalidArgumentException: Value "No environment" is invalid
```
Moreover, even if you were able to select by value (`No environment`), you'll get an integer instead of a string:
```
Failed asserting that '0' is identical to 0.
```
For more consistency, the solution is to always return a string.
The issue does not exist in 2.6, as the `QuestionChoice::getDefaultValidator` handled things differently.
