FrameSinkVideoCapturer: Ensure resurrected frames are up-to-date w/ source.

This fixes a minor logic flaw, where a resurrected frame could be used
in some rare cases where it would not contain the most up-to-date

the |dirty_rect_|, but that means that those frame captures have to
complete *before* any future resurrected frame would be guaranteed to be
up-to-date.
