Returning back from any app [after share via] is creating a black screen

When the surfaceView is destroyed during compositing, ContentViewRenderView
can't receive the message. So, the onSwapBuffers event will not occurs, and the
value of mPendingSwapBuffers will increasing without bound.

To prevent the problem, currently, the value is initialized in onReadyToRender
method. However, content_shell and chromium_test_shell override the method and
don't call super method.
