Simplified the Travis test command

There is no reason to turn a failure into a different failure. And this
will avoid Travis to say that the "false" command failed.

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 PR https://github.com/symfony/symfony/commit/466a3d70b7972dbac20264c254351ca31ee5c476 introduced a BC break because white spaces were previously decoded as text nodes.

So this PR reverts it and adds a context option to configure it.

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).

Improving the exception message when the bundle name is wrong for the controller in a route

Usually, it is wrong because you've chosen the wrong bundle name in your _controller syntax.
But this also tries to imply that you *might* be missing your bundle initialization in AppKernel
(though I think this is much much less common).
