Fix setup of adding _flash_types test.

Adding flash types to a controller within any of the tests will result
in a global state change of the controller under test.

This patch will prevent state leaks and allow us to run the test in random order.

Ignore order when doing count.

This is necessary because Postgresql doesn't play nice with ORDER BY and
no GROUP BY.

Fixes #14621.

Use connection-specific bytea escaping

In our normal usage, it's rare for this to make a difference... but is
more technically correct.

As well as a spec that proves this is a good idea, let's also add a more
sane-looking one that just covers basic to_sql functionality. There
aren't many places where we actually use escape_bytea, but that's one
that won't be going away.

Build the reverse_order on its proper method.

The reverse_order method was using a flag to control if the order should
be reversed or not. Instead of using this variable just build the reverse order
inside its proper method.

This implementation was leading to an unexpected behavior when using
reverse_order and then applying reorder(nil).

Example:
  Before
    Post.order(:name).reverse_order.reorder(nil)
    # => SELECT "posts".* FROM "posts"   ORDER BY "posts"."id" DESC

  After
    Post.order(:name).reverse_order.reorder(nil)
   # => SELECT "posts".* FROM "posts"
