Notice: Undefined index: revision_id in field_collection_field_get_entity() line 1685

Problem/Motivation

Not a critical but the module throws an error message:
"Notice: Undefined index: revision_id in field_collection_field_get_entity() line 1685"

In my case I see this error message after feeds importer finishes the process. It doesn't break the import process but shows the message only when it ends.

Steps to reproduce

I haven't tried in other scenarios but these steps I follow in this specific case:

• I have a content type where is set a field as a field_collection type
• There is a feeds importer configured to import content from external link, this is configured to run with cron
• Run manually (UI or Drush) cron
• When it finishes throws the error message

Proposed resolution

There is a single condition missing in field_collection.module line 1685

if ($entity && $entity->revision_id != $item['revision_id']) {

The proposed solution is:

if ($entity && isset($item['revision_id']) && $entity->revision_id != $item['revision_id']) {

I'm leaving a patch for review.
