 		upsert() now requires a value for every primary key column 
A record missing a primary key value - or with None for one - can
never match an existing row, because a NULL primary key never
satisfies ON CONFLICT. Such records were previously inserted as
brand new rows (silently, for multi-record upsert_all calls) or
triggered a KeyError after the insert had already happened. Both
cases, including upserting an empty record, now raise
PrimaryKeyRequired before any SQL is executed.

d2bcdc00c6 Swapped the order of a bunch of pytest comparisons 
When I wrote this I thought constant == value was a better assertion. I no longer think that.
