[TwigComponent] Fix full context is stored in profiler

As $event->getVariables() get the full context for non-embed components, this led to huge data stored
for every component called during the request.

As this is internal data, and the "variables" was not used in the profiler, I believe we should consider this a bug
and simply remove it.
