Remove help wanted text from README

Despite some great work done in the last couple of months, nobody showed a strong motivation to take over this project.

I want to thank @hkdobrev for his hard work as he helped me lot in closing issues and fixing bugs. Silex is now compatible with Symfony 4 and that's going to help a lot in migrating projects.

I still strongly believe that Symfony 4 is a better alternative and that there is nothing unique anymore in Silex.

Forking is still an option if someone wants to take over of course.

Check for HttpKernelRuntime before using it in Twig runtimes

Fixes #1448.

This fixes an incompatibility with Symfony Twig bridge prior to 3.2.

The HttpKernelRuntime was introduced in https://github.com/silexphp/Silex/commit/72d7746ec216da230221c19aa6e3092b55596070.
It included checks whether the class exists, but not in the Twig runtimes list.
