Behavior for og_membership_delete_action

Problem/motivation

OG actions do not set behavior parameter key used by VBO (see e.g. https://www.drupal.org/node/2052067). In this case VBO uses default behavior value array('changes_property').

However when an action has changes_property behavior, VBO re-saves the entity after executing the action.

I.e. for og_membership_delete_action action VBO tries to re-save a membership entity after having deleted it. Though it doesn't re-creates the membership entity, it causes executing hook_og_membership_update() which is confusing.

Proposed solution

Set behavior for og_membership_delete_action explicitly to array('deletes_property').
