Description of change

Closes #11858

This provides a much better error message for the situation described in #11858.

However it is technically a breaking change because on Postgres running SELECT FROM "Foos" does not throw (simply yielding an empty array). However from the Sequelize point of view, it should throw (IMO), since why would you run a SELECT query and fetch nothing?

Note: The commit as in PR title other(find-all): throw on empty attributes is not allowed by commitlint because other is not a valid scope type. However, I am unsure of what choice to make among the valid options, which are build, ci, docs, feat, fix, perf, refactor, revert, style and test, so I leave it for you to decide @sushantdhiman. I ended up putting fix(find-all) in the actual commit message, but on squash-and-merge that won't matter much.

Tests are breaking. I don't think it is a good idea, what if you got includes or scopes are injecting attributes.

Hi @sushantdhiman, you are right, however I still think something could be done about these errors, so I worked on another approach. Tests are passing now, please review again, thanks!
