RETURN does not accomodate returned paths

**Describe the bug**
RETURN does not return a tuple of paths in its current syntax and form.

**How are you accessing AGE (Command line, driver, etc.)?**
- AGE ver. 1.4.0 based on the current main branch.

**What data setup do we need to do?**
Have a database.

**What is the command that caused the error?**
```pgsql
SELECT * FROM cypher('matrix', $$ MATCH (a)-[]->(b) RETURN (a)-[]-(b)$$) as (a agtype);
```
```
ERROR: must be scalar value, not array or object
```

**Expected behavior**
According to the OpenCypher specification, This query should return a tuple of elements that satisfy the MATCH requirement.

**Environment (please complete the following information):**
- Version: [e.g. 1.6.0], latest main branch. This should be reproducible in any version of Postgres.
