fix(symfony): make WriteListener compatible with MainController

While "data" is set in the context in the MainController, this was not the case with the WriteListener.

I noticed this after updating from v3.2.14 to v3.3.3. Although I had set `event_listeners_backward_compatibility_layer` to `false`, the Symfony events were used again instead of the `MainController`. I had to set `use_symfony_listeners` to false so that I could restore the behavior of v3.2.14.

Shouldn't `use_symfony_listeners` be `false` if `event_listeners_backward_compatibility_layer` is also set to `false`?
