Document suggestion

As a user with document suggestions
I want to see the proper document content
So that I understand the content I need to select

Details

Current suggestions only show value. This means that on document references, document Uid is shown. The id is not the correct human value to provide the user as it might not be easy only by this to really identify the user. So, we need to show more details ie, thumbnail and title.

Server behaviour:  a proposal is to enrich the suggestion with default document enrichment.

UI behaviour:  present thumbnail and title. on selection, the value still needs to be the ID (actually the directory enrichement json should be the value to give the input) as in the document suggestor.

So, needs to be compatible with document suggestion.

Suggestion UI

Left: thumbnail.

Right: Title (ellipses) first line; Path (ellipses, smaller font) second line. 

Tooltip on the suggestion should present the full tittle followed by the full path.
