Merge branch 'ds/remove-idx-before-pack'

We create .pack and then .idx, we consider only packfiles that have
.idx usable (those with only .pack are not ready yet), so we should
remove .idx before removing .pack for consistency.

* ds/remove-idx-before-pack:
  packfile: delete .idx files before .pack files
