merge: filter actions before calling _resolvetrivial() In d49e490a9e85252886fd43258803bcad4fc88edb I made _resolvetrivial() to be called after upadting the sparse checkout. Looking at the code now, it seems to that me there is no need to even run _resolvetrivial() on actions which are filtered away. So let's update the actions before passing them into _resolvetrivial().
