Suggest misattributed author roles update, on taylored entity types

[jum-s]

Since #434, one may edit alternative author role properties for works and series, depending on their P31 value.

This author roles "tayloring" should now allow to suggest to the user when a role should not belong to an entity P31 (misattributed author roles) ie. a screenwriter for a written work.

Implementation suggestions:

• always display the correct possible roles properties
• display flag icon à la Wikidata values constraints below the incorrect property (would allow to display the reason on hover on touch)
