Fallback formatter doesn't display with Entity Reference

Issue:
When using Editable Fields as the Display formatter for an Entity Reference field, and the fallback formatter set to "entityreference_*", if the user views a node and does not have permission to edit, the fallback formatter is never displayed.

Expected behaviour:
The fallback formatter renders the field.

I tracked this down to the fact that the entityreference formatters expect field_prepare_view to have been called to load extra info about the entity. Editable fields clones the entity in editablefields_fallback_formatter, but it doesn't set $cloned_entity->_field_view_prepared to false. So, the entityreference formatter assumes that its hook_field_prepare_view had been called and doesn't load the entity data, resulting in the field not being shown.
