evolve: store obsmarkers to be deleted in evolvestate
There are operations which don't create a new node rather they just obsolete one
of the unstable node in favour of existing one. In such cases if a further
resolution leads to conflicts and user calls `evolve --abort` or `evolve
--stop`, we might need to delete that obsmarker. So let's store such obsmarkers
in the evolvestate.
