Description:
We have situations where _field or some other RQG built-in is not capable of returning a valid value, so we return an empty string, which almost certainly does not make sense in the grammar, producing an SQL syntax error, while the test continues to run.

An example would be using _fields_indexed with a ZZ file that does not define any indexes.

Such situations must be converted into assertions. This way, both the grammar and the RQG itself will be tested. In other words, the grammar should not be allowed to run with _fields_indexed if the ZZ file does not specify any indexes, and the RQG should never return an empty _tables due to some internal problem.

How to repeat:
see above
