Fix the calling `merge` method at first in a scope
Changing the order of method chaining `merge` and other query
method such as `joins` should produce the same result.
```ruby
class Topic < ApplicationRecord
scope :safe_chaininig, -> { joins(:comments).merge(Comment.newest) }
scope :unsafe_chaininig, -> { merge(Comment.newest).joins(:comments) } #=> NoMethodError
end
```
