Human readable message on view compaction error
Human readable message on view compaction error

When a view has duplicated document IDs in the main btree,
the view compactor exists. Unfortunatelly its exit reason is
not human readable because it's an IOList.
This patch improves the error message and logs it with an
'error' level.

Issue reported by Mike Leddy in ticket COUCHDB-999.
