Fix listing of deep paths in PostgreSQL backend (#2393)

Browse Source 
This change addresses an issue where deep paths would not be enumerated if parent paths did not contain a key.

Given the keys `shallow` and `deep` at the following paths...
```
secret/shallow
secret/path/deep
```

... a `LIST` request against `/v1/secret` would produce only one result, `shallow`.  With this change, the same list request will now list `shallow` and `path/`.
