low-code-connectors: handle single records

[girarda]

What

Some exchanges only wrap their records in a list if there's more than 1. They return the raw records otherwise.
The selector is expected to return a list of records, so it should wrap the output if the extractor did not return a list.

How

• Check if the object returned by the extractor is a list or not.
