Fix compactor crash when .compact file is missing header
Users affected by COUCHDB-968 can take advantage of this patch to
force a compaction in retry mode and thus remove the duplicates.
Simply create an empty dbname.couch.compact file in the database_dir
before triggering the compaction for dbname.
