enhance: Entity.pk() default provided that uses id

[ntucker]

Motivation

More terse common case.

Solution

Outcome

• Entity with no pk() override will use the id member
• In DEV mode normalize with missing id will alert user they need to override Entity.pk()

Changes

• Remove Entity's special abstract pk() type (schema.Entity mixin already defaults to this.id)
• Add special error message in EntitySchema.normalize() when default implementation is used but id is not present
