Handle AsapoDataNotInCacheError in AsapoReceiver

In case the data is not in the cache any more, the data is lost, and
thus a MissingDataError is raised for an AsapoDataNotInCacheError.

SimpleAsapoReceiver can now also throw a MissingDataError, but this
should be ok as a worker either expects this error or it falls back to
the defaul no-op handler.
