Subject: [PATCH] Fix get_real_name for names with more than two dotted parts
 (#332)

get_real_name anchored on the first dot (via token_next_by), so it
returned the second component of a fully-qualified name. For a 2-part
name the first dot is also the last, so it was accidentally correct;
for 3+ parts it returned an intermediate component:

    parse("db.schema.tbl.col")[0].tokens[0].get_real_name()
    # 'schema', should be 'col'

The object name is the component after the last dot. Anchor on the last
dot instead. get_parent_name still uses the first dot, as documented, so
parent/real name now come from opposite ends as intended.
