Unexpected interface error for query_single[_json]

**Describe the bug**

Query single methods raise unexpected error without executing the query

**Reproduction**
Use `_example` project

```python
await db.query_single_json(
'select Movie {**} filter .release_year = $release_year',
release_year=32
)
```
raises
````
InterfaceError('query cannot be executed with query_single_json() as it may return more than one element')
````

**Expected behavior**
I would expect the behavior that is described in the docs:
The query must return no more than one element. If the query returns more than one element, an `edgedb.ResultCardinalityMismatchError` is raised, if it returns an empty set, "null" is returned

So the expected behavior is no exception except when multiples entries are returned
