Subject: [PATCH] Make `Comparer.is_match` property work ...

... for an `errors` dictionary full of
inspectors without any errors, for example:

```
{
    'columns': {},
    'primary_keys': {},
    'foreign_keys': {},
    'indexes': {},
    'unique_constraints': {},
    'check_constraints': {},
}
```
