Resources provided based on entityreference fields have changed their name

The Services Entity Reference submodule defines relationships on entity types for the backward reference from entityreference fields.

In other words, if entity type Foo has an entityreference field which points to Bar entities, then the Bar entity type has a relationship resource defined on it.

The name of this resource was the pluralized machine name of the entity on which the field is, 'foo'.

However, this causes problems if there are multiple fields on entity type Foo which all point to Bar entities.

Hence, the resource name is now formed from the pluralized machine name and the fieldname:

$name . '_' . $field_name
