function civicrm_entity_reference_field_entity_presave in CiviCRM Entity 7.2

Implements hook_entity_presave().

We needed this because sometimes you need to back fill a value before save

For example, if you put a civicrm entity reference field which targets the location block, on a event entity, you have to make sure the event gets a value for the location_block_id Another example is that the location block address_id property needs to be set after the address is saved (considering if you have an civicrm_entity_reference field on the location block form, targeting address

More cases of this type may crop up and we'll better understand how to automate as time passes and experience hits us over the head
