To ensure that a model BooleanField has an explicit value set (and since it's

not required, by default), set the default properly in the constructor.

This code can be simplified when/if we resolve the
BooleanField/NullBooleanField overlap, but the current stuff is backwards
compatible. This would previously cause SQL errors on PostgreSQL and
interesting failures in subtle ways on MySQL and SQLite.
