Improve handling of defaults (inc provider default clauses, literal defaults, and QGIS expression defaults) and automatically handle unique value constraints on layers
Any fields with unique value constraints will be guaranteed to have a value which is unique to the field.
This also means that after certain editing operations (e.g. copy-paste, split features etc.) attributes will now be set to their default value, if applicable.
