pgsql: Add parse location fields to NullTest and BooleanTest structs.

Add parse location fields to NullTest and BooleanTest structs.

We did not need a location tag on NullTest or BooleanTest before, because
no error messages referred directly to their locations. That's planned
to change though, so add these fields in a separate housekeeping commit.

Catversion bump because stored rules may change.
