merge: remove redundant unlink after merge

The early prescan for move/remove and removal of moved files in applyupdates
was introduced with mergestate 368a4ec603cc and rendered this chunk of code
irrelevant.

The impact of the chunk was reduced in 5b3383ea67d2 - but it could have been
removed completely.
