Don't send resize messages until the renderer has been initialized.

[Retry of 14260 with fixed unit test.]

1) Moves renderer_initialized_ from RenderWidgetView into RenderWidgetHost (its parent).  Should be identical semantics to before.
2) Test renderer_initialized_ in RWH::WasResized().

This also reverts r13725, which was another attempt at fixing this problem.

BUG=9830,10659
TEST=From the Linux start page, click a link then click back -- should not get a gray page.  From Google reader, click a link (which spawns a new tab within the same process) -- should not get a gray page.
