Fixes a rare race in phase 1 of garbage collection, as described in
more detail in the commit message of patch 2.
This patches are intended as stop gap for the time being, until a
different approach to guarantee the presence of index files also
after pruning has been explored and implemented, as suggested by
Thomas [0].

Changes since version 3:
- Refactor open_index_reader to allow distinction between missing index
  file and ignored archive type blob.
- Iterate snapshots from newest to oldest to further reduce race window
  and simplify accounting logic.
