Breaking changes

• Storage backends no longer support the ignore_conflict
  argument (#1401). Instead of using this argument, consider catching the
  UnicityError and handling it. ignore_conflict was only ever
  used in one place, in the default_bucket plugin, and was
  eventually backed out in favor of catching and handling a
  UnicityError.

Bug fixes

• Fix a TOCTOU bug in the Postgres storage backend where a transaction
  doing a create() would fail because a row had been inserted after
  the transaction had checked for it (#1376).
