Fix bug #7164967 android.view.cts.ViewGroup_MarginLayoutParamsTest#testResolveMarginsRelative failures on JO

This was a regression introduced by a previous CL.

- we actually need to let the layout params resolution goes all the time
as we dont have any "isResolved" state and a public API for doing its reset thru ViewGroup.

The current implementation is simple and works even if it is doing sometimes a bit more
than it should really do. This is a well conscious tradeoff.
