This fixes flushing test databases when two aliases point to the same
database.
Use a list() to store the test database aliases so the order remains
stable by following the order of the connections. Also, always use the
"default" database alias as the first alias to accommodate `migrate`.
Previously `migrate` could be executed on a secondary alias which
caused truncating the "default" database.

The subquery pushdown only happens because another table is involved in
filter. It's not the distinct usage that causes the pushdown.
The distinct('description').order_by('pk') expression is not valid
because SELECT DISTINCT ON must match initial ORDER BY expressions
which is not the case here.

Since this example was added 15 years ago in a8ccdd0fcd631e8e928ef20547e1fe3e313dc607, the ORM has gained the ability to do the `COUNT(*)` related query, so do it with the ORM to avoid misleading users that raw SQL is only supported from manager methods.

This disables interpolation of constraint creation statements. Since
Constraint.create_sql interpolates its parameters instead of deferring
this responsibility to the backend connection it must disable
connection level parameters interpolation.
