On Windows, this test case fails with:

```
1) Symfony\Bridge\PsrHttpMessage\Tests\Factory\PsrHttpFactoryTest::testUploadErrNoFile
RuntimeException: The file "C:\projects\symfony" cannot be opened: fopen(C:\projects\symfony): Failed to open stream: Permission denied
```

The reason is that the empty string is turned into the empty directory, and you can't fopen a directory on Windows.

The removed assertion have no purpose, they only check the behavior of the native SplFileInfo class.
