Only enable symfony error handler in debug mode

[jkrzefski]

I don't know why the Symfony error handler is always enabled. Maybe there is a deeper meaning behind it that I don't see. But if not, I propose to only use Debug when debugging is requested (via config or command option).

Not so sure about this one, if the server crashes (during the bridge bootstrap, for example) there might be very little info about what happened. Did you run some tests on it?

[jkrzefski]

No, I did not run any tests on my end. I only looked through the code, spotted this and thought it looked wrong. The travis build seems fine, though.

I am totally ok with leaving it the way it was. I would merely like a short explanation on why the error handler is enabled in production. Maybe a comment in the code would be nice, so others don't get confused like I was.

Enable during startup and disable after first client answer sent?

Could you propose what you'd expect?
