BView/BBox: Fixed FrameResized() handling.

* BView incorrectly passed the current width and height to
  FrameResized(), not the one from the message. Since there is such
  a call for each size change, a Draw() might have been called for
  each of those in return.
* This should also fix such problems in BMenuBar, as it used the size
  from FrameResized() as it should have.
* BBox now correctly takes the update events into account, and no
  longer ignores the size passed to FrameResized().
* This fixes bug #3037.
