The parent constructor will create a new formatter if the $formatter parameter is null.

This fix avoids that the formatter becomes 2 different instances in $this and $this->stderr, if null was passed to the constructor.

There is no reason to turn a failure into a different failure. And this

Although it is not directly described in gettext docs, _msgid_ should be unescaped too. The other reason to unescape _msgid_ is symmetry between ```PoFileLoader``` and ```PoFileDumper```. The dumper escapes both _msgid_ and _msgstr_ values, but the loader unescapes only _msgstr_.

The Expression Language isn't a dependency of the SecurityBundle, but ExpressionVoter is still added if it isn't installed, leading to a class not found fatal error. This removes the services (alternatively the services could be moved to a different file and added if it is installed).

The syntax check functionality has been removed in PHPUnit 3.6 already. But there's no Composer constraint for PHPUnit, so you can never know which version will actually be used to run tests. Let me know what you think.
