test: fix ioredis tests

[rauno56]

Which problem is this PR solving?

Some of the assertions are done in the hooks in the tests for ioredis.

1. The errors thrown in the hooks are eaten, so no benefit having them there,
2. Even if they aren't one of them was validating an ever-increasing counter, which can ever only be correct once,
3. Test for scan broke when there were more than 10 keys in the DB - not a problem when running on a clean DB every time, but happens locally when tests occasionally completely fail and the cleanup will not happen.

Short description of the changes

• Added sinon to move the assertions in the hooks outside of them.
• Tweaked scan tests with match and count parameters
• Narrowed down the TAV version set - if we expect devs to ever run them, it better not take an hour. It currently takes 2 minutes.
