mergestate: explicitly forget 'dc' conflicts where the deleted side is picked

Once we move change/delete conflicts into the resolve phase, a 'dc' file might
first be resolved by picking the other side, then later be resolved by picking
the local side. For this transition we want to make sure that the file goes
back to not being in the dirstate.

This has no impact on conflicts during the initial merge.
