Now that HTTPParser uses MakeCallback it is unnecessary to manually
process the nextTickQueue.

The KickNextTick function is now no longer needed so code has moved back
to node::MakeCallback to simplify implementation.

Include minor cleanup moving Environment::tick_info() call below the
early return to save an operation.

Make comment clear that Undefined() is returned for legacy
compatibility. This will change in the future as a semver-major change,
but to be able to port this to previous releases it needs to stay as is.

The second argument of the post callback is a boolean indicating whether
the callback threw and was intercepted by uncaughtException or a domain.

Currently node::MakeCallback has no way of retrieving a uid for the
object. This is coming in a future patch.

Rather than abort if the init/pre/post/final/destroy callbacks throw,
force the exception to propagate and not be made catchable. This way
the application is still not allowed to proceed but also allowed the
location of the failure to print before exiting. Though the stack itself
may not be of much use since all callbacks except init are called from
the bottom of the call stack.
