Title: Remove some test warnings

These `table` variables are giving warnings and doesn't seem to be required for such tests.

I'm also getting this warning when running tests:

arel/lib/arel/nodes/window.rb:21: warning: instance variable @frame not initialized

The warning is in this method:

```ruby
def frame(expr)
raise ArgumentError, "Window frame cannot be set more than once" if @frame
@framing = expr
end
```

Where I believe the `@frame` variable should actually be `framing`, but this gives me 2 failing tests in `test_select_manager.rb`. I'll try to take a look into this later, but any directions are welcome. Thanks.
