Fix suppression for WindowProxy::initializeIfNeeded to match on release builds.

Fix suppression for WindowProxy::initializeIfNeeded to match on release builds.

Due to 484760, symbolization for WindowProxy::initializeIfNeeded is
different between debug and release builds, which causes the current
suppression to not match on the try bots.  On release builds, it comes
up as: > #8 0x7875c74 in initializeIfNeeded
third_party/WebKit/Source/bindings/core/v8/WindowProxy.cpp:209:19

Use blink::WindowProxy::createContext instead.
