fix/sim: fix incorrect implementation of compound select generation
...
Problem:
sim was generating compound selects like this:
- pick a random `table`
- create a random single SELECT
- create `n` random compound SELECTs (UNION ALL etc)
assign a WHERE clause that always has a condition based on `table`
This can result in e.g.
```
SELECT a FROM foo WHERE bar.x = 'baz'
```
Solution:
Don't base the WHERE clause on a table that might not be referenced
in the query.
Again, the only reason this wasn't caught before was because `FaultyQuery`
and `FsyncNoWait` are the only paths where this is actually tested with an
assertion, and those are both disabled

* IO never ran in step loop inside simulator.

debugging).
