Use `count(:all)` in HasManyAssociation#count_records
Problem: Calling `count` on an association can cause invalid SQL queries
to be created where the `SELECT COUNT(a, b, c)` function receives
multiple columns. This will cause a `StatementInvalid` exception later
on.
Solution: Use `count(:all)`, which generates a `SELECT COUNT(*)...`
query independently of the association.
This also includes a test case that, before the fix, broke.
