provide defaults for all keywords and subschemas that lacked them (#1006)

Add or remove defaults as appropriate including where redundant

- Remove `default` from all subschemas that recursively-reference #meta
- Add `default to `dependencies`

Remove, e.g. when evaluating the "not" keyword, the subschema inside it should *not* be true, as that would produce a false result from this keyword.
