Use getPathname() instead of string casting to get BinaryFileReponse file path

According to the code, should be "File" instead of "\SplFileInfo"

[Finder] Escape location for regex searches

If the location to start searching in contains a regex special char
like + or ? and the path restriction is a regular expresion with a start
limitation. No results will be found wtih at least GnuFindAdapter - e.g.:
```
use Symfony\Component\Finder\Finder;
use Symfony\Component\Finder\Adapter;

mkdir('/tmp/reg+ex/dir/subdir', 0777, true);

$finder = Finder::create()
    ->removeAdapters()
    ->addAdapter(new Adapter\GnuFindAdapter());
$finder->in('/tmp/reg+ex')->path('/^dir/');

print count($finder)."\n";
```

Expected result: 2
Actual result is: 0

This pull request consists of:
* a new test checking for this bug (0e81086a49425d0e12cff4f479fabeb97e9ed757)
* the actual fix (6595b6b2b71afc57ef08686b4584713c0e4e48ed)
* changes to comply with the coding standard (7f199c5b53b3c1f38b36dcc286d3b20ae877425b)

## How to reproduce
### Fastest way
1. Move or copy your local symfony clone into a location containing special regex chars:
  * `mv symfony symfony+regex`
2. Run tests in there
  * `cd symfony+regex && phpunit`

> Result: Some tests in the finder component will fail.

### Alternative: A new clone
1. Clone symfony in a directory containing at least one regex special char
  * `git clone https://github.com/symfony/symfony.git /tmp/symfony+regexchar`
2. As usual get composer, install dependencies and get phpunit
  * You might simply want to follow [this guide](http://symfony.com/doc/current/contributing/code/tests.html)
3. Run tests in there
   * `cd /tmp/symfony+regexchar && phpunit`

> Result: Some tests in the finder component will fail.

### Alternative: Apply the new test
1. Apply commit a29d1207ced2949c918357cf271200523960caef to your symfony clone
2. Run tests

> Result: The new test will fail.

If libxml_use_internal_errors is set to `true` before parsing xliff file, the libxml errors are not cleared correctly. An error `Validation failed: no DTD found !` occurs in libxml errors after parsing and it's available outside the xliff parser (can break other functionality that use `libxml_get_errors` function).
