commit 07fbfbeb17a03c6872562bd8da226cacf023aafd
Author: Yuki Shiino <yukishiino@chromium.org>
Date: Sat Nov 25 05:06:27 2017

v8binding: Uses the safe v8::Context in callback functions.

It turned out that ScriptState::GetContext will be gone before
the destruction of the ScriptState.  This patch uses the safest
v8::Context when throwing an exception.
