Migrations produce warnings about rendered item fields

[mjordan]

Running both the migrate_islandora_csv and islandora_7x migrations from the command line produces the following warning for each node:

[warning] Warning: While indexing items on search index Default Solr content index, 1 item(s) did not have a view mode configured for one or more "Rendered item" fields.

To fix this manually:

1. before import navigate to the solr index fields configuration page (http://localhost:8000/admin/config/search/search-api/index/default_solr_index/fields)
2. Click on the 'Edit' link on the "rendered_item" line
   
3. Select a view mode (I recommend "Search index") for each of the content types and click "Save"
   (Note: screenshots taken from future.islandora.ca that has a bunch of extra content types at the time of capture.)
4. Click "Save changes" at the bottom of the page.

Existing content (if you have any) will need to be reindexed.

I've tried to set sensible defaults, export the search settings as part of the islandora feature, but for some reason I can't import them back in. We will need to rely on documentation, for now.
