Follow up for #1801304-313: Add Entity reference field Task C
Problem/Motivation
After picking entity reference for the display type,
if you scroll down to the preview section, you will see: red error: 'Display "EntityReference" needs a selected search fields to work properly. See the settings for the Entity Reference list format.'
But solution is go up and click on the format link and to pick the only option in a required setting. Silly to make a human do that.
Proposed resolution
Have EntityReference display default to whatever the "primary field" is of the given view type
OR
Despite being scary, the message is descriptive, so click on "Settings" next to Entity Reference list. Suggest: just link right there from the error message directly
Remaining tasks
Discuss how this can be implemented
User interface changes
No UI changes.
API changes
Maybe API changes.

FEEDBACK:
In a similar way that the Views wizard defaults to having User: Name field already populated, can the EntityReference display default to whatever the "primary field" is of the given view type?FOLLOW-UP: Had the error been at the top of the page, I could've reacted faster. Not the fault of this patch. (I don't think.)
