Add parse location fields to NullTest and BooleanTest structs.

Browse Source 
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.
