Refactor `NullRelation#calculate`
Before:
```ruby
def calculate(operation, _column_name)
if [:count, :sum].include? operation
group_values.any? ? Hash.new : 0
elsif [:average, :minimum, :maximum].include?(operation) && group_values.any?
Hash.new
else
nil
end
end
```
After:
```ruby
def calculate(operation, _column_name)
case operation
when :count, :sum
group_values.any? ? Hash.new : 0
when :average, :minimum, :maximum
group_values.any? ? Hash.new : nil
end
end
```
