merge: pass mergeresult obj in _forgetremoved() (API)

Instead of returning a dict of actions and then updating it, let's pass the
object directly and update it there.

This makes `updateactions()` on mergeresult unused and this patch removes that.

After this patch, we have couple of methods left on mergeresult class which
still exposes the internal dict based action storage.
